INTEGRAL observations of the GeV blazar PKS1502+106 and of the hard X-ray bright Seyfert Galaxy Mkn841
E. Pian, P. Ubertini, A. Bazzano +15
Extragalactic nuclear activity is best explored with observations at high energies, where the most extreme flux and spectral variations are expected to occur, witnessing changes in…
An X-ray view of the INTEGRAL/IBIS blazars
S. Gianni', A. De Rosa, L. Bassani +3
Aim of this work is a broad-band study with INTEGRAL, Swift and XMM-Newton satellites of a sample of 9 blazars (7 FSRQ and 2 BL Lac) with redshift up to about 4. The spectral analy…
IGR J16328-4726: a new candidate Supergiant Fast X-ray Transient
M. Fiocchi, V. Sguera, A. Bazzano +4
The unidentified source IGR J16328-4726 was covered with INTEGRAL observations for a long period (~9.8Ms) and was undetectable for most of the time while showing a very recurrent m…
The Proposed High Energy Telescope (HET) for EXIST
J. Hong, J. Grindlay, B. Allen +10
The hard X-ray sky now being studied by INTEGRAL and Swift and soon by NuSTAR is rich with energetic phenomena and highly variable non-thermal phenomena on a broad range of timesca…
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…
Five new INTEGRAL unidentified hard X-Ray sources uncovered by Chandra
M. Fiocchi, L. Bassani, A. Bazzano +4
The IBIS imager on board INTEGRAL, with a sensitivity better than a mCrab in deep observations and a point source location accuracy of the order of few arcminutes, has localized so…
