Cross-correlation of the 2XMMi catalogue with Data Release 7 of the Sloan Digital Sky Survey
F. -X. Pineau, C. Motch, F. Carrera +5
The Survey Science Centre of the XMM-Newton satellite released the first incremental version of the 2XMM catalogue in August 2008 . With more than 220,000 X-ray sources, the 2XMMi…
Suzaku and SWIFT-BAT observations of a newly discovered Compton-thick AGN
P. Severgnini, A. Caccianiga, R. Della Ceca +4
Obscured AGN are fundamental to understand the history of Super Massive Black Hole growth and their influence on galaxy formation. However, the Compton-thick AGN (NH>1e24 cm^-2) po…
High redshift Fermi blazars
G. Ghisellini, G. Tagliaferri, L. Foschini +6
With the release of the first year Fermi catalogue, the number of blazars detected above 100 MeV lying at high redshift has been largely increased. There are 28 blazars at z>2 in t…
Overview of EXIST mission science and implementation
J. Grindlay, N. Gehrels, J. Bloom +14
The Energetic X-ray Imaging Survey Telescope (EXIST) is designed to i) use the birth of stellar mass black holes, as revealed by cosmic Gamma-Ray Bursts (GRBs), as probes of the ve…
Revealing the First Stellar and Supermassive Black Holes to EXIST
J. Grindlay, J. Bloom, P. Coppi +8
The epochs of origin of the first stars and galaxies, and subsequent growth of the first supermassive black holes, are among the most fundamental questions. Observations of the hig…
The Soft X-ray Imager on board EXIST
L. Natalucci, A. Bazzano, F. Panessa +11
The Soft X-ray Imager (SXI) is one of the three instruments on board EXIST, a multi-wavelength observatory in charge of performing a global survey of the sky in hard X-rays searchi…
Chasing the heaviest black holes of jetted Active Galactic Nuclei
G. Ghisellini, R. Della Ceca, M. Volonteri +7
We investigate the physical properties of the 10 blazars at redshift greater than 2 detected in the 3-years all sky survey performed by the Burst Alert Telescope (BAT) onboard the…
