The EXIST view of Super-Massive Black Holes in the Universe
Roberto Della Ceca, Gabriele Ghisellini, Gianpiero Tagliaferri +9
With its large collection area, broad-band energy coverage from optical/NIR (0.3 to 2.2 micron) to soft/hard X-ray (0.1-600 keV), all-sky monitoring capability, and on-board follow…
GALEX measurements of the Big Blue Bump as a tool to study bolometric corrections in AGNs
Elena Marchese, R. Della Ceca, A. Caccianiga +2
Active Galactic Nuclei emit over the entire electromagnetic spectrum with the peak of the accretion disk emission in the far-UV, a wavelength range historically difficult to invest…
Heavily obscured AGN in the local Universe
P. Severgnini, A. Caccianiga, R. Della Ceca +4
We present here a new powerful diagnostic plot to select heavily obscured AGN in the local universe by combining infrared (Spitzer, IRAS) and X-ray (XMM) information. On the basis…
The SXI telescope on board EXIST: scientific performances
L. Natalucci, A. Bazzano, S. Campana +9
The SXI telescope is one of the three instruments on board EXIST, a multiwavelength observatory in charge of performing a global survey of the sky in hard X-rays searching for Supe…
A Suzaku observation of the ULIRG IRAS19254-7245: disclosing the AGN component
V. Braito, J. N. Reeves, R. Della Ceca +3
We discuss here a long Suzaku observation of IRAS 19254-7245 (also known as the Superantennae), one of the brightest and well studied Ultra Luminous Infrared Galaxies in the local…
