A multi-wavelength survey of AGN in the XMM-LSS field: I. Quasar selection via the KX technique
Th. Nakos, J. P. Willis, S. Andreon +16
AIMS: We present a sample of candidate quasars selected using the KX-technique. The data cover 0.68 deg^2 of the X-ray Multi-Mirror (XMM) Large-Scale Structure (LSS) survey area wh…
The XMM large scale structure survey: optical vs. X-ray classifications of active galactic nuclei and the unified scheme
O. Garcet, P. Gandhi, E. Gosset +25
Our goal is to characterize AGN populations by comparing their X-ray and optical classifications. We present a sample of 99 spectroscopically identified X-ray point sources in the…
The XMM-LSS survey: the Class 1 cluster sample over the initial 5 square degrees and its cosmological modelling
F. Pacaud, M. Pierre, C. Adami +30
We present a sample of 29 galaxy clusters from the XMM-LSS survey over an area of some 5deg2 out to a redshift of z=1.05. The sample clusters, which represent about half of the X-r…
The XMM-LSS catalogue: X-ray sources and associated optical data. Version I
M. Pierre, L. Chiappetti, F. Pacaud +34
Following the presentation of the XMM-LSS X-ray source detection package by Pacaud et al., we provide the source lists for the first 5.5 surveyed square degrees. The catalogues per…
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…
