XMM-Newton first X-ray detection of the LoBAL quasar PG 1700+518
L. Ballo, E. Piconcelli, C. Vignali +1
We report the first high-energy detection of PG 1700+518, a well-known low-ionization broad absorption line quasar (QSO). Due to previous X-ray non-detection, it was classified as…
Demography of obscured and unobscured AGN: prospects for a Wide Field X-ray Telescope
R. Gilli, P. Tozzi, P. Rosati +7
We discuss some of the main open issues in the evolution of Active Galactic Nuclei which can be solved by the sensitive, wide area surveys to be performed by the proposed Wide Fiel…
AGN unified scheme and evolution: a Suzaku view
A. Comastri, K. Iwasawa, R. Gilli +2
We present broad band Suzaku}observations of a small sample of hard X-ray selected (> 10 keV), nearby Seyfert 2 galaxies and discuss the results in the context of AGN unified model…
The gravitationally lensed, luminous infrared galaxy IRAS F10214+4724 observed with XMM-Newton
K. Iwasawa, C. Vignali, A. S. Evans +2
We report on a short XMM-Newton observation of the gravitationally-lensed, luminous infrared galaxy IRAS F10214+4724 at z=2.3. A faint X-ray source is detected at 4 sigma. The obse…
The Chandra COSMOS Survey, I: Overview and Point Source Catalog
Martin Elvis, Francesca Civano, Cristian Vignali +40
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exp…
The Growth of Supermassive Black Holes Across Cosmic Time
K. Nandra, J. A. Aird, D. M. Alexander +54
One of the main themes in extragalactic astronomy for the next decade will be the evolution of galaxies over cosmic time. Many future observatories, including JWST, ALMA, GMT, TMT…
