The Bright Side of the Hard X-ray Sky: The XMM-Newton Bright Survey
R. Della Ceca, A. Caccianiga, P. Severgnini +3
We discuss here the main goals and some interesting results of the "XMM-Newton Bright Serendipitous Survey", a research program conducted by the XMM-Newton Survey Science Center in…
The HELLAS2XMM survey. IX. Spectroscopic identification of super-EROs hosting AGNs
R. Maiolino, M. Mignoli, L. Pozzetti +12
We present VLT near-IR spectroscopic observations of three X-ray sources characterized by extremely high X-ray-to-optical ratios (X/O>40), extremely red colors (6.3<R-K<7.4, i.e. E…
Dating the stellar population in massive early-type galaxies at 1.5
M. Longhetti, P. Saracco, P. Severgnini +7
We present the analysis of 10 massive early-type galaxies at . They have been identified by means of a near-IR low resolution spectroscopic follow-up of a complete sample…
The first optical validation of an XLEO: a detection in the XMM-Newton observation of the CDFS
V. Braito, T. Maccacaro, A. Caccianiga +2
We present the first optical validation of an X-ray Line-Emitting Object (XLEO) discovered in the XMM-Newton observation of the Chandra Deep Field South. The object is an AGN at z_…
