Deep XMM-Newton survey of M33

In a GT raster observation of the bright local group spiral galaxy M33 we study the population of Xray sources (SNRs, XRBs, supershells) down to a0.12.4 keV luminosity limit of 10E35erg/s a factor of 10 deeper thanearlier ROSAT observations. EPIC spectra and hardness ratios are used toseparate between different source classes. We search for short term timevariability, pulsations of the order of 1 to few 100 s and long termvariability, i.e. binary light curves, transients. We spectrallycharacterize the diffuse component that is correlated with the inner spiralarms. Here, we repropose observations that were dominated by high EPICbackground or used EPIC with the thick filter. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
