TL;DR: The 2XMM catalogue as mentioned in this paper is the largest ever made at X-ray wavelengths, containing 246 897 detections drawn from 3491 public XMM-Newton observations over a 7-year interval, which relate to 191 870 unique sources.

TL;DR: In this article, the authors report on the production of a large area, shallow, sky survey, from XMM-Newton slews, in three distinct energy bands; a soft (0.2 −2 keV) band, a hard (2 −12 keV)-band and a total XMMNewton band (0 −12 −3 keV).

TL;DR: In this article, a statistically complete sample of 28 serendipitous X-ray sources selected in 82 pointed XMM-Newton fields down to a count-rate of 0.002 counts s(-1) (4.5-7.5 keV energy band).

TL;DR: In this paper, the authors constrain the extragalactic source count distributions over a broad range of X-ray fluxes and in various energy bands to test whether the predictions from Xray background synthesis models agree with the observational constraints provided by their measurements.

TL;DR: In this article, the distribution of the power-law energy index for this sample has a mean of 0.81 and shows significant intrinsic dispersion, σ = 0.31, values which are broadly compatible with those from samples of lower luminosity active galactic nuclei.
