Obscured and unobscured AGN populations in a hard-X-ray selected sample of the XMDS survey
M. Tajer, M. Polletta, L. Chiappetti +16
Our goal is to probe the populations of obscured and unobscured AGN investigating their optical-IR and X-ray properties as a function of X-ray flux, luminosity and redshift within…
Spectral Energy Distributions of Hard X-ray selected AGNs in the XMDS Survey
M. Polletta, M. Tajer, L. Maraschi +18
We present the spectral energy distributions (SEDs) of a hard X-ray selected sample. The sample contains 136 sources with F(2-10 keV)>10^-14 erg/cm^2/s and 132 are AGNs. The source…
The Butcher--Oemler effect at z~0.35: a change in perspective
S. Andreon, H. Quintana, M. Tajer +2
The present paper focuses on the much debated Butcher-Oemler effect: the increase with redshift of the fraction of blue galaxies in clusters. Considering a representative cluster s…
The XMM-LSS survey: The XMDS/VVDS 4 sigma catalogue
L. Chiappetti, M. Tajer, G. Trinchieri +15
We present a first catalogue of X-ray sources resulting from the central area of the XMM-LSS (Large Scale Structure survey). We describe the reduction procedures and the database t…
A sample of X-ray emitting normal galaxies from the BMW -- HRI Catalogue
M. Tajer, G. Trinchieri, A. Wolter +3
We have obtained a sample of 143 normal galaxies with X-ray luminosity in the range erg s from the cross-correlation of the ROSAT HRI Brera Multi-scale W…
