The ASCA HSS: Looking for Type 2 AGN
R. Della Ceca, V. Braito, V. Beckmann +2
We will briefly discuss the X-ray spectral properties of the objects in the ASCA Hard Serendipitous Survey (HSS) sample and its present AGN contents. We also present X-ray spectros…
BeppoSAX broad-band observations of low-redshift quasars: Spectral curvature and iron K_alpha lines
T. Mineo, F. Fiore, A. Laor +7
We present results from BeppoSAX observations of 10 low redshift quasars. The quasars are part of the Laor et al. (1997) sample of 23 optically selected PG quasars with redshift <0…
The Most Distant X-ray Clusters and the Evolution of their Space Density
P. Rosati, S. Borgani, R. Della Ceca +3
We briefly review our current knowledge of the space density of distant X-ray clusters as measured by several ROSAT serendipitous surveys. We compare old and new determinations of…
A Hard Medium Survey with ASCA. III.: a Type 2 AGN revealed from X-ray Spectroscopy
R. Della Ceca, T. Maccacaro, P. Rosati +1
In this paper we report the discovery of an hard X-ray selected Type 2 Seyfert galaxy and we present and discuss its X-ray and optical spectrum together with the radio to X-ray ene…
