M 83 XMM-Newton X-Ray Point Source Catalog

The X-ray luminosity function inside the D25 ellipse is consistent with that previously observed by Chandra. The Kolmogorov-Smirnov test shows that the X-ray luminosity function of the outer disc and the AGN luminosity distribution are uncorrelated with a probability of ~99.3%. The authors also found that the X-ray sources detected outside the D₂₅ ellipse and the uniform spatial distribution of AGNs are spatially uncorrelated with a significance of 99.5%.

They interpret these results as an indication that part of the observed X-ray sources are X-ray binaries in the outer disc of M 83. The authors analyzed the public archival XMM-Newton data of M 83 (PIs: Watson, Kuntz). Three observations were analyzed, one pointing at the center of the galaxy (obs.1) and two in the south, which covered the outer arms with a young population of stars discovered with GALEX.

The details of these observations are given in Table 1 of the reference paper (summarized below): <pre> EPIC EPIC EPIC No ObsID Date RA DE PN MOS1 MOS2 Mode F Texp F Texp F Texp PN MOS 1 0110910201 2003-01-27 13:37:05.16 -29:51:46.1 t 21.2 m 24.6 m 24.6 EFF FF 2 0503230101 2008-01-16 13:37:01.09 -30:03:49.9 m 15.4 m 19.0 m 19.0 EFF FF 3 0552080101 2008-08-16 13:36:50.87 -30:03:55.2 m 25.0 m 28.8 m 28.8 EFF FF </pre> where F is the filter (t for thin, m for medium), T_exp is the exposure time in ks, EFF = extended full frame imaging mode, and FF = full frame imaging mode.
