The broad-band properties of the XMM-Newton Bright Serendipitous Sources
R. Della Ceca, T. Maccacaro, A. Caccianiga +2
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 pr…
The TESIS project: Are type 2 QSO hidden in X-ray emitting EROs?
P. Severgnini, R. Della Ceca, V. Braito +8
Here we present the results obtained from the analysis of 75 ksec of XMM-Newton observations of a sample of EROs selected from one MUNICS field (K'<19.5 mag). We find 6 EROs with a…
The TESIS project: revealing massive early-type galaxies at z>1
P. Saracco, M. Longhetti, P. Severgnini +8
We present the preliminary results of an on-going near-IR low resolution spectroscopic follow-up of a complete sample of 30 bright (K'<18.5) EROs selected over 360 arcmin^2 from th…
The TNG EROs Spectroscopic Identification Survey (TESIS)
P. Saracco, M. Longhetti, R. Della Ceca +8
We are carrying on a near-IR very low resolution spectroscopic follow-up in parallel with XMM-Newton observations of a complete sample of ~30 bright (K'<18.5) Extremely Red Objects…
The Ultra Luminous Infrared Galaxy MKN 231: New clues from BeppoSAX and XMM-Newton
V. Braito, R. Della Ceca, E. Piconcelli +11
We present BeppoSAX and XMM-Newton observations of MKN 231. These observations and in particular the BeppoSAX PDS data allowed us to unveil, for the first time, the highly absorbed…
