Title:	The multiwavelength survey of the ELAIS-S1 field
Authors:	Fiore, Fabrizio Buonanno, Roberto Feruglio, Chiara
Issue Date:	26-Nov-2008
Abstract:	This thesis presents and discusses an analysis of the multiwavelength obser- vations (from mid-infrared to X-rays) of the central 0.6 square degrees of the ELAIS-S1 field . It makes use of data from four great observatories: XMM-Newton selects a large sample of Active Galactic Nuclei (AGN), so disclosing the accretion processes onto super-massive black holes (SMBH), Chandra provides arcsec positions for the X-ray sources, ESO/VLT provides photometry, spectroscopy (redshift and source classification), and the Spitzer mid-infrared bands probe obscured AGNs and dusty star-forming galaxies. The main main goals of this survey are: 1) to obtain a complete census of accreting SMBHs population in the Universe, combining different selection methods, and 2) to study the AGN environment and compare it to that non accreting passive and star-forming galaxies. 1) Unobscured and moderately obscured AGNs are selected using hard X-ray data, while obscured AGNs can be selected using mid-inf...
