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…
