We propose Spitzer observations with both IRAC and MIPS of a well defined sample of hard X-ray selected obscured AGN serendipitously discovered by XMM-Newton in the 2-10 keV band. The key scientific issues we plan to address with the proposed broad-band infrared observations are: (a) A solid estimate of the bolometric luminosity of accretion-powered, obscured sources and of the correlations between hard X-ray properties (luminosity, obscuration, spectral slope) and infrared spectral energy distribution. (b) To recover the nuclear spectral energy distribution of those AGN for which the presence of supermassive black hole is inferred from the X-ray emission but which remains elusive from observations at optical-UV and near-infrared wavelengths. (c) A probe of the physical status of the dense circumnuclear matter responsible of the X-ray obscuration and dust reprocessed infrared emission by comparison with the AGN unified model predictions. The proposed sample, selected from a shallow, large area, hard X-ray survey (HELLAS2XMM), contains the most luminous members of the population of highly obscured AGN responsible for the X-ray background. It is thus well suited for a pilot Spitzer program (40 hours) which will allow us to investigate the so far poorly known spectral energy distribution of luminous, obscured Type II quasars in the mid-and far-infrared domains.
