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…
Multi-wavelength data handling in current and future surveys: the possible role of Virtual Observatory
C. Vignali, F. Fiore, A. Comastri +5
Here we review some of the main issues related to multi-wavelength source identification and characterization, with particular emphasis on the field of X-ray surveys carried out ov…
Revealing X-ray obscured quasars in SWIRE sources with extreme mid-IR/optical flux ratios
G. Lanzuisi, E. Piconcelli, F. Fiore +4
Recent works have suggested that selection criteria based on MIR colors can be used to reveal a population of dust-enshrouded, extremely luminous quasars at z>1. However the X-ray…
