- Description:
- The enhanced 3XMM catalogue (designated 3XMMe) is one of the core elements of the Arches project, representing the X-ray source basis for the cross-correlations with other multi-wavelength catalogues. The 3XMMe catalogue is a derivative of the latest increment of the 3XMM catalogue, i.e. 3XMM-DR5, that was publicly released in April 2015 (Rosen et al., 2016A&A...590A...1R, Cat. XI/46)), tailored for the purposes of the Arches project. The 3XMM-DR5 catalogue, available from the XMM-Newton Science Archive (http://xmm.esac.esa.int/xsa/), the XMM-Newton Survey Science Centre (SSC) (http://xmmssc.irap.omp.eu) and other sites listed on the SSC site, contains 565962 detections arising from 396910 unique sources drawn from 7781 XMM observations. These numbers include detections from 356 sub-pointings made in mosaic mode. Arches wed site : http://www.arches-fp7.eu .

- Description:
- The present catalog summaries the results of a survey carried out on one of the deepest X-ray field observed by the XMM-Newton satellite. The survey is made by 13 observations taken over 2 years with a total exposure time of 1.75Ms (1.372Ms for flare-filtered) in a field of 30'x30' around the blazar 1ES 1553+113. Using a conservative threshold of Maximum Likelihood significance of ML>=6, we detected 301 X-ray point-sources, for which we derived positions, fluxes at different bands and hardness ratios. Thanks to an optical follow-up by the Gran Telescopio Canarias (GTC) over the same field in u'g'r'i'z' bands, we obtained an optical source list of 43,068 elements with photometric redshift. We cross correlated this optical source list and an infrared catalog obtained by WISE with photometric measurements in the W1, W2, W3 and W4 bands, with our X-ray catalog. We identified optical/IR counterpart candidates for our X-ray sources and we estimated their X-ray luminosities, redshift distribution, X-ray/optical flux ratio and absolute magnitudes. Additionally, we identify a subset of 204 AGNs, for which we classified as: Quasar, Seyfert galaxies and Low Luminous AGNs (LLAGNs), based on their luminosities.

- Description:
- We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observatory during Performance Verification. The X-ray data of the Lockman Hole field and the derived cumulative source counts were reported by Hasinger et al. (2001A&A...365L..45H). We restrict the analysis to the sample of 98 sources with more than 70 net counts (flux limit in the [0.5-7]keV band of 1.6x10^-15^erg/cm^2^/s) of which 61 have redshift identification. We find no correlation between the spectral index and the intrinsic absorption column density NH and, for both the Type-1 and Type-2 AGN populations, we obtain <Gamma>~=2.

- The XMM-Newton 2nd Incremental Source Catalogue (2XMMi)
- Short Name:
- IX/40
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- Description:
- The 2XMMi catalogue is the fourth publicly released XMM X-ray source catalogue produced by the XMM Survey Science Centre (SSC) consortium, following the 1XMM (Cat. IX/37, released in April 2003), 2XMMp (July 2006) and 2XMM (Cat. IX/39, August 2007) catalogues: 2XMMp was a preliminary version of 2XMM. 2XMMi is an incremental version of the 2XMM catalogue. The 2XMMi catalogue is about 17% larger than the 2XMM catalogue, which it supersedes, due to the 1-year longer baseline of observations included (it is about 8 times larger than the 1XMM catalogue). As such, it is the largest X-ray source catalogue ever produced, containing more than twice as many discrete sources as either the ROSAT survey or pointed catalogues. 2XMMi complements deeper Chandra and XMM-Newton small area surveys, probing a large sky area at the flux limit where the bulk of the objects that contribute to the X-ray background lie. The 2XMMi catalogue provides a rich resource for generating large, well-defined samples for specific studies, utilizing the fact that X-ray selection is a highly efficient (arguably the most efficient) way of selecting certain types of object, notably active galaxies (AGN), clusters of galaxies, interacting compact binaries and active stellar coronae. The large sky area covered by the serendipitous survey, or equivalently the large size of the catalogue, also means that 2XMMi is a superb resource for exploring the variety of the X-ray source population and identifying rare source types. The production of the 2XMMi catalogue has been undertaken by the XMM-Newton SSC consortium in fulfilment of one of its major responsibilities within the XMM-Newton project. The catalogue production process has been designed to exploit fully the capabilities of the XMM-Newton EPIC cameras and to ensure the integrity and quality of the resultant catalogue through rigorous screening of the data. The predecessor 2XMM catalogue was made from a subset of public observations emerging from a re-processing (in 2006/7) of all XMM observations made prior to that point. The creation of the incremental 2XMMi catalogue has been driven by the desire to make public the additional data from that re-processing that were proprietary at the time of the 2XMM release but which subsequently became public before 01 May 2008. These have been augmented with a further 90 observations that have been processed more recently as part of the routine, day-to-day XMM data processing performed by the SSC, which were also public at 01 May 2008. Together, these amount to 626 additional observations (18%) with respect to 2XMM. With these new data, the sky area covered grows by 19% while the number of detections increases by 17% and the number of unique sources by 15%. A key factor in the decision to make the 2XMMi catalogue is the fact that, effectively, all the new data have been processed with the same science analysis software (SAS), pipeline and calibration as used in the aforementioned re-processing. As such, the products from 2XMM and from the new observations form a set of uniformly processed data. With software and calibration changes now being propagated into the SSC processing pipeline, it was deemed timely to make public the largest available uniform catalogue. The catalogue in its FITS version file (2xmmi.fit) has 246897 entries made of 297 columns; a 'slim' version gathering the 39 most relevant columns for the 191870 unique sources detected, is available as an ascii table or a FITS binary table. In both versions, the columns are fully described in the XMM-Newton User Guide available from: http://xmmssc-www.star.le.ac.uk/Catalogue/UserGuide_xmmcat.html The original names of these columns are included in the "Byte-by-byte Description" below (uppercase names within parentheses) Details about the construction of the catalogue can be found from the XMM-Newton Survey Science Centre (http://xmmssc-www.star.le.ac.uk/)

- Description:
- 2XMM is the second comprehensive catalogue of serendipitous X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory. The catalogue has been constructed by the XMM-Newton Survey Science Centre (SSC) on behalf of ESA. It is the largest X-ray source catalogue ever produced, containing almost twice as many discrete sources as either the ROSAT survey or pointed catalogues. The catalogue contains source detections drawn from 3491 XMM-Newton EPIC observations covering a sky area of about 360 square degrees, made between 2000 February 3 and 2007 March 31; all datasets were publicly available by 2007 May 01 but not all public observations are included in this catalogue. The catalogue contains 246897 X-ray source detections which relate to 191870 unique X-ray sources. The median flux in the total photon energy band (0.2-12keV) of the catalogue detections is about 2.5x10^-14^erg/cm2/s (25aW/m2). About 20% of the sources have total fluxes below 10^-14^erg/cm2/s (10aW/m2). The catalogue in its FITS version file (xmm2cat.fit) has 246897 entries made of 297 columns; a 'slim' version gathering the 39 most relevant columns for the 191870 unique sources detected, is available as an ascii table or a FITS binary table.

- 3XMM-DR7s serendipitous source catalogue from stacks
- Short Name:
- IX/56
- Date:

- Publisher:
- CDS
- Description:
- XMM-Newton has observed the X-ray sky since the beginning of 2000. The XMM-Newton Survey Science Centre Consor-tium has been publishing catalogues of X-ray and ultraviolet sources found serendipitously in the individual observations. This series is now augmented by a catalogue dedicated to X-ray sources detected in spatially overlapping XMM-Newton observations. This catalogue aims at exploring repeatedly observed sky regions. It thus makes use of the long(er) effective exposure time per sky area and offers the opportunity to investigate long-term flux variability directly through the source detection process. A new standardised strategy for simultaneous source detection on multiple observations is introduced, including an adaptive-smoothing method to describe the image background. It is coded as a new task edetect_stack within the XMM-NewtonScience Analysis System and used to compile a catalogue of sources from 434 stacks comprising 1789 overlapping XMM-Newtonobservations that entered the 3XMM-DR7 catalogue and have a low background and full-frame readout of all EPIC cameras. The first stacked catalogue is called 3XMM-DR7s. It contains 71 951 unique sources with positions and source parameters like fluxes, hardness ratios, quality estimate, and information on inter-observation variability, which are directly derived from a simultaneous fit and calculated for the stack and for each contributing observation. More than 8 000 sources are new with respect to3XMM-DR7. By stacked source detection, the parameters of repeatedly observed sources can be determined with higher accuracy than in the individual observations. It is more sensitive to faint sources and tends to produce fewer spurious detections. With this first catalogue we demonstrate the feasibility and benefit of the approach. It supplements the large data base ofXMM-Newton detections by additional, in particular faint, sources and new variability information. In the future, it will be expanded to larger samples and continued within the series of serendipitous XMM-Newton source catalogues

- 4XMM-DR9s serendipitous source catalogue from stacks
- Short Name:
- IX/61
- Date:

- Publisher:
- CDS
- Description:
- The XMM-Newton Survey Science Centre Consortium (SSC) develops software in close collaboration with the Science Operations Centre to perform a pipeline analysis of all XMM-Newton observations. In celebration of the twentieth anniversary of the XMM-Newton launch, the SSC has compiled the fourth generation of serendipitous source catalogues, 4XMM. The catalogue described here, 4XMM-DR9s, explores sky areas that were observed more than once by XMM-Newton. These observations are bundled in groups referred to as stacks. Stacking leads to a higher sensitivity, resulting in newly discovered sources and better constrained source parameters, and unveils long-term brightness variations. The 4XMM-DR9s catalogue was constructed from simultaneous source detection on overlapping observations. As a novel feature, positional rectification was applied beforehand. Observations with all filters and suitable camera settings were included. Exposures with a high background were discarded. The high-background thresholds were determined through a statistical analysis of all exposures in each instrument configuration. The X-ray background maps used in source detection were modelled via an adaptive smoothing procedure with newly determined parameters. Source fluxes were derived for all contributing observations, irrespective of whether the source would be detectable in an individual observation. The new catalogue lists the X-ray sources detected in 1329 stacks with 6604 contributing observations over repeatedly covered 300 square degrees in the sky. Most stacks are composed of two observations, the largest one comprises 352 observations. We find 288191 sources of which 218283 were observed several times. The number of observations of a source ranges from 1 to 40. Auxiliary products, like X-ray full-band and false-colour images, long-term X-ray light curves, and optical finding charts, are published as well. 4XMM-DR9s contains new detections and is considered a prime resource to explore long-term variability of X-ray sources discovered by XMM-Newton. Regular incremental releases, including new public observations, are planned.

- Description:
- The XMM-Newton observatory is a cornerstone mission of the European Space Agency (ESA) Horizon 2000 program. This spacecraft, the largest ever flown by ESA for a scientific program, was launched on December 10, 1999, carrying a payload funded by ESA member states and the USA (NASA). The scientific payload comprises three CCD imaging cameras (European Photon Imaging Cameras, EPIC), sensitive in the 0.1-15 keV band, and two Reflecting Grating Spectrometers (RGS), sensitive in the 0.3-2.1 keV band, and characterized by a resolving power E/{Delta}E = 100 to 800. The X-ray instruments are complemented by an Optical Monitor, sensitive in the 150-650nm band, which allows simultaneous multiwavelength monitoring of celestial sources. The XMM-Newton observational program is determined on the bases of the proposals sent in response to Announcement of Opportunities, and selected by peer review panels. The XMM-Newton Science Archive (XSA) contains all the science data of all the performed observations. Its user interface (http:xmm.vilspa.esa.es/xsa) allows a user to retrieve them after the 1-year proprietary period has expired. Calibration observations are normally not covered by proprietary rights; their data being therefore public. Target of Opportunity and Discretionary Time observations have a 6-months proprietary period. For each archived observation, the XSA stores Observation Data Files (ODF) and Pipeline Processing System (PPS) products, if available, as well as the XMM-Newton EPIC serendipitous catalogue, the OM source catalogue and the Slew Survey Source Catalogue (see the catalogues documentation at http://xmm.esac.esa.int/xsa). The ODF comprises raw telemetry files, reformatted in FITS format, and contains uncalibrated information. The PPS products are a collection of top-level, validated scientific and cross-correlation products, routinely generated by the Science Survey Center, University of Leicester, UK (http://xmmssc-www.star.le.ac.uk). The content of the XSA is updated daily. The latest version of all the scientific data is made available through its interface. Systematic reprocessing of all the XMM-Newton telemetry is periodically carried on during the mission. The last bulk reprocessing was performed in 2007. The XMM-Newton observation log lists all the science observations included in the XSA. This log gives observation details and provides links to quick-look scientific products, to documents describing XMM-Newton science and calibration data, and to the SAS (Science Analysis System), a specific software package designed to reduce and analyze XMM-Newton data. Additional links in the log allows a user to start a retrieval session for the data of an observation, whenever not protected by proprietary rights.

- XMM-Newton Serendipitous Source Catalogue (1XMM)
- Short Name:

- Publisher:
- CDS
- Description:
- 1XMM is the first comprehensive catalogue of serendipitous X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory launched in December 1999, and has been constructed by the XMM-Newton Survey Science Centre (SSC) on behalf of ESA. Most (>80%) of the entries have not previously been reported as X-ray sources. The catalogue contains source detections drawn from 585 XMM-Newton EPIC observations made between 2000 March 1 and 2002 May 5; all datasets were publicly available by 2003 January 31 but not all public observations are included in this catalogue. Net exposure times in these observations range from less than 1000 up to about 100000 seconds. The total area of the catalogue fields is about 90deg^2^, but taking account of the substantial overlaps between observations, the net sky area covered independently is about 50deg^2^. The observations sample, albeit sparsely, most of the sky, with the exception of a 'hole' centered in the Cygnus region, caused by spacecraft observing constraints. The catalogue source detection and parametrization technique is optimized for point-like sources, and has been performed across several photon-energy bands (see "EPIC energy bands" below) and using data from each of the three EPIC cameras PN, MOS-1, MOS-2; the prefixes PN_ M1_ M2_ are generally used to designate the columns of the catalogue related to the detections by the corresponding camera. The catalogue in its FITS version has ~ 400 columns; these include source-detection parameters (likelihood, position coordinates, counts, count rate, flux, hardness ratio, background estimates, errors etc), the results of cross-correlation with a large number of archival catalogues (SIMBAD, NED, USNO, GSC, APM, ROSAT etc), quality 'flags' resulting from visual screening, and 'meta-data' relating to the observation. For practical considerations the ascii version of the catalogue is made of 3 tables representing the sources, the observations and processing details, and the results of the cross-correlations; the names used as column names in the ASCII version are also reported within parentheses in the "Byte-by-Byte" descriptions below. Details about the construction of the catalogue can be found from the XMM-Newton Survey Science Centre (http://xmmssc-www.star.le.ac.uk/)

Should you use the catalogue for your research and publish the results, please use the acknowledgement below and cite the paper describing 3XMM (Rosen, Webb, Watson et al., 2016A&A...590A...1R). This research has made use of data obtained from the 3XMM XMM-Newton serendipitous source catalogue compiled by the 10 institutes of the XMM-Newton Survey Science Centre selected by ESA. The following table gives an overview of the statistics of the catalogue in comparison with the 3XMM-DR4 catalogue. ---------------------------------------------------------------------------- 3XMM-DR6 3XMM-DR5 Increment ---------------------------------------------------------------------------- Number of observations 9160 7781 1379 Number of 'clean' observations (i.e., observation class < 3) 5947 4735 1212 Observing interval 03-Feb-00 03-Feb-00 2.5yr 04-Jun-15 20-Dec-13 Sky coverage, taking overlaps into account ( >=1ks exposure) 982sq.deg 877sq.deg 105sq.deg Number of detections 678680 565962 112718 Number of 'clean' detections (i.e., summary flag < 3) 552991 456904 96087 Number of unique sources 468440 396910 71530 Number of 'cleanest' (summary flag = 0, not in high-background fields) extended detections 11066 9082 1984 Number of detections with spectra 149968 133032 16936 Number of detections with timeseries 149968 133025 16943 Number of detections where probability of timeseries being constant is <1x10^-5^ 5238 4668 570 ---------------------------------------------------------------------------- The production and content of the 3XMM catalogue is described in the the 3XMM-DR6 User Guide at http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR6/3XMM-DR6_Catalogue_User_Guide.html The "slim" version of the catalogue (file "xmm3r6s.dat") contains one row per unique source, while the the main catalogue has one row per detection. This slim version includes 44 columns, essentially those containing information about the unique sources, while the full catalogue (file "xmm3r6.fit") describes all detections with 323 columns. The slim version also contains a column with links to the summary pages in the IRAP catalogue archive. In the case of sources with multiple detections the summary page of the best detection is selected (i.e., the detection with the largest exposure time, summed over all cameras), and the summary page gives cross-links to the other detections. A separate file "summary.dat" contains the key details about the observations used in the construction of the 3XMM-DR6 catalogue.

- Description:
- Sky surveys produce enormous quantities of data on extensive regions of the sky. The easiest way to access this information is through catalogues of standardised data products. XMM-Newton has been surveying the sky in the X-ray, ultra-violet and optical bands for 20 years. The XMM-Newton Survey Science Centre has been producing standardised data products and catalogues to facilitate access to the serendipitous X-ray sky. Using improved calibration and enhanced software we re-reduced all of the 14041 XMM-Newton X-ray observations. 11204 observations contained data with at least one detection and with these we created a new, high quality version of the XMM-Newton serendipitous source catalogue, 4XMM-DR9. 4XMM-DR9 contains 810795 detections down to a detection significance of 3{sigma}, of which 550124 are unique sources, that cover 1152-degrees^2^ (2.85%) of the sky. Filtering 4XMM-DR9 to retain only the cleanest sources with at least a 5{sigma} detection significance leaves 433612 detections. 99.6% of these detections have no pileup. 336 columns of information on each detection are provided, along with images. The quality of the source detection is shown to have improved significantly with respect to previous versions of the catalogues. Spectra and lightcurves are also made available for more than 288000 of the brightest sources (36% of all detections).

- Description:
- Thanks to the large collecting area (3x~1500cm^2^ at 1.5keV) and wide field of view (30' across in full field mode) of the X-ray cameras on board the European Space Agency X-ray observatory XMM-Newton, each individual pointing can result in the detection of hundreds of X-ray sources, most of which are newly discovered. Recently, many improvements in the XMM-Newton data reduction algorithms have been made. These include enhanced source characterisation and reduced spurious source detections, refined astrometric precision of sources, greater net sensitivity for source detection and the extraction of spectra and time series for fainter sources, with better signal-to-noise. Further, almost 50% more observations are in the public domain compared to 2XMMi-DR3, allowing the XMM-Newton Survey Science Centre (XMM-SSC) to produce a much larger and better quality X-ray source catalogue. The XMM-SSC has developed a pipeline to reduce the XMM-Newton data automatically and using improved calibration a new catalogue version has been made from XMM-Newton data made public by 2013 Dec. 31 (13 years of data). Manual screening ensures the highest data quality. This catalogue is known as 3XMM. In the latest release, 3XMM-DR5, there are 565962 X-ray detections comprising 396910 unique X-ray sources. For the 133000 brightest sources, spectra and lightcurves are provided. For all detections, the positions on the sky, a measure of the detection quality, and an evaluation of variability is provided, along with the fluxes and count rates in 7 X-ray energy bands, the total 0.2-12keV band counts, and four hardness ratios. To identify the detections, a cross correlation with 228 catalogues is also provided for each X-ray detection. 3XMM-DR5 is the largest X-ray source catalogue ever produced. Thanks to the large array of data products, it is an excellent resource in which to find new and extreme objects.

- Description:
- The 2XMMi-DR3 catalogue is the fifth publicly released XMM X-ray source catalogue produced by the XMM Survey Science Centre (SSC) consortium on behalf of ESA. It follows the 1XMM (Cat. IX/37, released in April 2003), 2XMMp (July 2006), 2XMM (Cat. IX/39, August 2007) and 2XMMi (Cat. IX/40, August 2008) catalogues: 2XMMp was a preliminary version of 2XMM. 2XMMi and 2XMMi-DR3 are incremental versions of the 2XMM catalogue. In summary, the versions are: -------------------------------------------- Name DR# Designation Year Cat. -------------------------------------------- 2XMMp 0 2XMMp-DR0 2006 2XMM 1 2XMM-DR1 2007 IX/39 2XMMi 2 2XMMi-DR2 2008 IX/40 2XMMi-DR3 3 2XMMi-DR3 2010 IX/41 -------------------------------------------- The production and content of the 2XMM catalogue is described in detail in "The XMM-Newton serendipitous survey. V. The second XMM-Newton serendipitous source catalogue", M.G. Watson et al., 2009A&A...493..339W; there are no significant differences in the processing between the 2XMM, 2XMMi and 2XMMi-DR3 observations The "slim" version of the catalogue (file "xmm2r3s.dat") contains one row per unique source, while the the main catalogue has one row per detection. This slim version includes 38 columns, essentially those containing information about the unique sources, while the full catalogue (file "xmm2r3.fit") describes the 353191 detections with 299 columns. The slim version also contains a column with links to the LEDAS summary pages. In the case of sources with multiple detections the summary page of the best detection is selected (i.e., the detection with the largest exposure time, summed over all cameras), and the summary page gives cross-links to the other detections.

- Description:
- We report on the production of a large area, shallow, sky survey, from XMM-Newton slews. The great collecting area of the mirrors coupled with the high quantum efficiency of the EPIC detectors have made XMM-Newton the most sensitive X-ray observatory flown to date. We use data taken with the EPIC-pn camera during slewing manoeuvres to perform an X-ray survey of the sky. Data from 218 slews have been subdivided into small images and source searched. This has been done in three distinct energy bands; a soft (0.2-2keV) band, a hard (2-12keV) band and a total XMM-Newton band (0.2-12keV). Detected sources, have been quality controlled to remove artifacts and a catalogue has been drawn from the remaining sources. A "full" catalogue, containing 4710 detections and a "clean" catalogue containing 2692 sources have been produced, from 14% of the sky. In the hard X-ray band (2-12keV) 257 sources are detected in the clean catalogue to a flux limit of 4x10^-12^erg/s/cm^2^. The flux limit for the soft (0.2-2keV) band is 6x10^-13^erg/s/cm^2^ and for the total (0.2-12keV) band is 1.2x10^-12^erg/s/cm^2^. The source positions are shown to have an uncertainty of 8" (1{sigma} confidence).

- Description:
- XMMSL2 is the second catalogue of X-ray sources found in slew data taken from the European Space Agency's (ESA) XMM-Newton observatory, and has been constructed by members of the XMM SOC and the EPIC consortium on behalf of ESA. This release uses results of work which has been carried out within the framework of the EXTraS project ("Exploring the X-ray variable and Transient Sky"), funded from the EU's Seventh Framework Programme under grant agreement no.607452. This is the first release of XMMSL2 which contains data taken between revolutions 314 and 2758. The previous catalogue was called XMMSL1_Delta6 and contained slews up to revolution 2441. The release includes two FITS files. A full catalogue (xmmsl2_total.fits.gz), containing 72352 detections found with a likelihood of DET_ML>8 and a "clean" catalogue (xmmsl2_clean.fits.gz) where all known bad sources have been removed and where the detection limit has been raised to DET_ML>10.5 in general and DET_ML>15.5 for sources found in images with a higher than usual background. Efforts have been made to identify spurious detections and 3017 have been flagged as such in the full catalogue.
