- Description:
- The 3XMM-DR7 catalogue contains source detections drawn from 9710 XMM-Newton EPIC observations, covering an energy interval from 0.2keV to 12keV. These observations were made between 2000 February 3 and 2016 December 15 and all datasets were publicly available by 2016 December 31, but not all public observations are included in this catalogue (see below for more information). 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-DR6 catalogue. --------------------------------------------------------------------------- 3XMM-DR7 3XMM-DR6 Increment --------------------------------------------------------------------------- Number of observations 9710 9159 551 Number of 'clean' observations 6164 5826 338 (i.e., observation class < 3) Observing interval 03-Feb-00 03-Feb-00 15-Dec-16 04-Jun-15 1.5 yr Sky coverage, taking overlaps into account ( >= 1ksec exposure) 1032sq.deg 982sq.deg 50sq.deg Number of detections 727790 678680 49110 Number of 'clean' detections 596268 552951 43317 (i.e., summary flag < 3) Number of unique sources 499266 468440 30826 Number of 'cleanest' (summary flag = 0, 11220 10290 930 not in high-background fields) extended detections Number of detections with spectra 162082 149998 12084 Number of detections with timeseries 162045 149968 12077 Number of detections where probability 5631 5238 393 of timeseries being constant is <1x10^-5^ --------------------------------------------------------------------------- The production and content of the 3XMM catalogue is described in the the 3XMM-DR7 User Guide at http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR7/3XMM-DR7_Catalogue_User_Guide.html The slimline version of the catalogue ( file "xmm3r7s.dat") contains one row per unique source (while the the main catalogue has one row per detection) and thus has 499266 rows. There are 44 columns, essentially those containing information about the unique sources. The catalogue also contains a column with links to the IRAP catalogue server 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:
- 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:
- 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:
- X-ray sources at intermediate fluxes (a few x10^-14^erg/cm^2^/s) with a sky density of ~100deg^-2^ are responsible for a significant fraction of the cosmic X-ray background at various energies below 10keV. The aim of this paper is to provide an unbiased and quantitative description of the X-ray source population at these fluxes and in various X-ray energy bands. We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comprises four largely overlapping source samples selected at soft (0.5-2keV), intermediate (0.5-4.5keV), hard (2-10keV) and ultra-hard (4.5-7.5keV) bands, the first three of them being flux-limited.

- Description:
- Pointed observations with XMM-Newton provide the basis for creating catalogues of X-ray sources detected serendipitously in each field. This paper describes the creation and characteristics of the 2XMM catalogue. The 2XMM catalogue has been compiled from a new processing of the XMM-Newton EPIC camera data. The main features of the processing pipeline are described in detail. The catalogue, the largest ever made at X-ray wavelengths, contains 246897 detections drawn from 3491 public XMM-Newton observations over a 7-year interval, which relate to 191870 unique sources. The catalogue fields cover a sky area of more than 500deg^2^. The non-overlapping sky are a is ~360deg^2^ (~1% of the sky) as many regions of the sky are observed more than once by XMM-Newton. The catalogue probes a large sky area at the flux limit where the bulk of the objects that contribute to the X-ray background lie and provides a major resource for generating large, well-defined X-ray selected source samples, studying the X-ray source population and identifying rare object types. The main characteristics of the catalogue are presented, including its photometric and astrometric properties The 2XMMi catalogue is available as Cat. <IX/40> in VizieR.

- 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:
- The on-going XMM-Newton Slew Survey (XSS) provides coverage of a significant fraction of the sky in a broad X-ray bandpass. Although shallow by contemporary standards, in the "classical" 2-10keV band of X-ray astronomy, the XSS provides significantly better sensitivity than any currently available all-sky survey. We investigate the source content of the XSS, focussing on detections in the hard 2-10keV band down to a very low threshold (>=4counts net of background). At the faint end, the survey reaches a flux sensitivity of roughly 3x10^-12^erg/cm^2^/s (2-10keV). Our starting point was a sample of 487 sources detected in the XSS (up to and including release XMMSL1d2) at high galactic latitude in the hard band. Through cross-correlation with published source catalogues from surveys spanning the electromagnetic spectrum from radio through to gamma-rays, we find that 45% of the sources have likely identifications with normal/active galaxies. A further 18% are associated with other classes of X-ray object (nearby coronally active stars, accreting binaries, clusters of galaxies), leaving 37% of the XSS sources with no current identification. We go on to define an XSS extragalactic sample comprised of 219 galaxies and active galaxies selected in the XSS hard band. We investigate the properties of this extragalactic sample including its X-ray logN-logS distribution. We find that in the low-count limit, the XSS is, as expected, strongly affected by Eddington bias. There is also a very strong bias in the XSS against the detection of extended sources, most notably clusters of galaxies. A significant fraction of the detections at and around the low-count limit may be spurious. Nevertheless, it is possible to use the XSS to extract a reasonably robust sample of extragalactic sources, excluding galaxy clusters. The differential logN-logS relation of these extragalactic sources matches very well to the HEAO-1 A2 all-sky survey measurements at bright fluxes and to the 2XMM source counts at the faint end. The substantial sky coverage afforded by the XSS makes this survey a valuable resource for studying X-ray bright source samples, including those selected specifically in the hard 2-10keV band.

- 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.
