- Description:
- In this paper we investigate the properties of low X-ray-to-optical flux ratio sources detected in a wide-area (2.5{deg}^2^) shallow [fX(0.5-8keV)~10^-14^erg/s/cm^2^] XMM-Newton survey. We find a total of 26 sources (5 per cent of the total X-ray-selected population) with log(fX)/f(opt)<-0.9 to the above flux limit. Optical spectroscopy is available for 20 of these low X-ray-to-optical flux ratio objects.

- Description:
- The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus Molecular Cloud, using the XMM-Newton X-ray observatory to study the thermal structure, variability, and long-term evolution of hot plasma, to investigate the magnetic dynamo, and to search for new potential members of the association. We present overall correlations with fundamental stellar parameters that were derived from the previous literature. The present overview paper introduces the project and provides the basic results from the X-ray analysis of all sources detected in the XEST survey. Comprehensive tables summarize the stellar properties of all targets surveyed. The survey goes deeper than previous X-ray surveys of Taurus by about an order of magnitude and for the first time systematically accesses very faint and strongly absorbed TMC objects. We find a detection rate of 85% and 98% for classical and weak-line T Tauri stars (CTTS resp. WTTS), and identify about half of the surveyed protostars and brown dwarfs. Overall, 136 out of 169 surveyed stellar systems are detected. We describe an X-ray luminosity vs. mass correlation, discuss the distribution of X-ray-to-bolometric luminosity ratios, and show evidence for lower X-ray luminosities in CTTS compared to WTTS.

- Description:
- We present the first results from the XMM-Newton Galactic Plane Survey (XGPS). In the first phase of the programme, 22 pointings were used to cover a region of approximately 3 deg^2^between 19{deg} and 22{deg} in Galactic longitude and +/-0.6{deg} in latitude. In total we have resolved over 400 point X-ray sources, at >=5{sigma} significance, down to a flux limit of ~2x10^-14^erg/s/cm^2^(2-10 keV).

- Publisher:
- CDS
- Description:
- The XMM-Newton survey of the Small Magellanic Cloud (SMC) yields a complete coverage of the bar and eastern wing in the 0.2-12.0keV band. This catalogue comprises 3053 unique X-ray point sources and sources with moderate extent that have been reduced from 5236 individual detections found in observations between April 2000 and April 2010. Sources have a median position uncertainty of 1.3" (1{sigma}) and limiting fluxes down to ~1*10^-14^erg/s/cm2 in the 0.2-4.5keV band, corresponding to 5*10^33^erg/s for sources in the SMC. Sources have been classified using hardness ratios, X-ray variability, and their multi-wavelength properties. In addition to the main-field (5.58deg^2^) available outer fields have been included in the catalogue, yielding a total field area of 6.32deg^2^. X-ray sources with high extent (>40", e.g. supernova remnants and galaxy cluster) have been presented by Haberl et al. (2012, Cat. J/A+A/545/A128)

- 13+38 XMM-Newton/ROSAT 1.4GHz radio catalog
- Short Name:
- J/MNRAS/352/131
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- Description:
- In order to determine the relationship between the faint X-ray and faint radio source populations, and hence to help understand the X-ray and radio emission mechanisms in those faint source populations, we have made a deep 1.4-GHz Very Large Array radio survey of the 13h+38{deg} XMMNewton/ROSAT X-ray Survey Area. From a combined data set of 10-h, B-configuration data and 14-h, A-configuration data, maps with 3.35-arcsec resolution and a noise limit of 7.5Jy were constructed. A complete sample of 449 sources was detected within a 30-arcmin diameter region above a 4 detection limit of 30Jy, at the map centre, making this one of the deepest radio surveys at this frequency. The differential source count shows a significant upturn at submilliJansky flux densities, similar to that seen in other deep surveys at 1.4GHz (e.g. the Phoenix survey, Cat. <J/MNRAS/296/839>), but larger than that seen in the Hubble Deep Field (HDF) which may have been selected to be underdense. This upturn is well modelled by the emergence of a population of medium-redshift star-forming galaxies which dominate at faint flux densities. The brighter source counts are well modelled by active galactic nuclei.

- XMM-Newton Serendipitous Source Catalogue (1XMM)
- Short Name:
- IX/37
- Date:

- 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/)

- XMM-Newton Serendipitous Source Catalogue 3XMM-DR5
- Short Name:
- IX/46
- Date:

- 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.
