The broad-band properties of the XMM-Newton Bright Serendipitous Sources

We present here “The XMM-Newton Bright Serendipitous Survey”, a survey program conducted by the XMM-Newton Survey Science Center. In particular we discuss the main goals of this project, we present the sample(s) and the current optical breakdown and we discuss some broad band spectral properties as derived from an hardness ratio analysis of the single sources. Finally we report the 4.5–7.5 keV Log(N$>$S)-LogS for type 1 and type 2 AGN.
