The XMM-Newton HBS28 sample: studying the obscuration in hard X-ray selected AGNs

A. Caccianiga, P. Severgnini, V. Braito +8

This paper presents the analysis of a statistically complete sample of 28 serendipitous X-ray sources selected in 82 pointed XMM-Newton fields down to a count-rate of 0.002 counts…

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 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…

A Hard Medium Survey with ASCA. IV: the Radio-Loud Type 2 QSO AXJ0843+294 2

R. Della Ceca, V. Braito, V. Beckmann +6

We discuss the X-ray, optical and radio properties of AX J0843+2942, a high luminosity Type 2 AGN found in the ASCA Hard Serendipitous Survey. The X-ray spectrum is best described…

An XMM-Newton hard X-ray survey of ULIRGs

A. Franceschini, V. Braito, M. Persic +8

XMM-Newton observations of 10 ULIRGs are reported. The aim is to investigate in hard X-rays a complete ULIRG sample selected from the bright IRAS 60m catalogue. All sources are…
