A deep XMM-Newton serendipitous survey of a middle-latitude area

The radio-quiet neutron star 1E1207.4-5209 was the target of a 260 ks XMM-Newton observation, that yielded, as a by product, a harvest of about 200 serendipitous X-ray sources above a limiting flux of 2 × 10^-15 erg cm^-2 s^-1 in the 0.3-8 keV energy range. In view of the intermediate latitude of our field (b≃ 10°), it comes as no surprise that the log N-log S distribution of our serendipitous sources is different from those measured either in the Galactic Plane or at high galactic latitudes. Here we concentrate on analyzing of the brightest sources in our sample, which unveiled a previously unknown Seyfert-2 galaxy.
