N. Sacchi,F. La Franca,Chiara Feruglio,Fabrizio Fiore,S. Puccetti,F. Cocchia,S. Berta,Marcella Brusa,A. Cimatti,Andrea Comastri,Alberto Franceschini,Carlotta Gruppioni,Roberto Maiolino,I. Matute,M. Polletta,Lucia Pozzetti,Francesca Pozzi,C. Vignali,G. Zamorani,S. J. Oliver,Michael Rowan-Robinson,Graham P. Smith,C. Lonsdale +22 more
TL;DR: In this article, a catalog of optical spectroscopic identifications of sources detected by Spitzer at 3.6 or 24 micron down to 10 and 280 microJy, respectively, in the SWIRE/XMM-Newton/ELAIS-S1 field was presented.
Journal ArticleDOI
The XMM deep survey in the CDF-S: VI. Obscured AGN selected as infrared power-law galaxies
N. Castelló-Mor,Francisco J. Carrera,A. Alonso-Herrero,Silvia Mateos,Xavier Barcons,Piero Ranalli,Pablo G. Pérez-González,Andrea Comastri,Cristian Vignali,I. Georgantopoulos +9 more
TL;DR: In this paper, a simple X-ray spectral model that includes a power-law modified by intrinsic absorption at the redshift of each source was adopted to measure the amount of intrinsic absorption in these sources.
Journal ArticleDOI
