The INTErnational Gamma Ray Astrophysics Laboratory: INTEGRAL Highlights
Ubertini, Pietro; Bazzano, Angela
The INTEGRAL Space Observatory was selected as the second Medium size mission (M2) of the ESAs Horizon 2000 vision programme. INTEGRAL is the first high angular and spectral resolution hard X-ray and soft γ-ray observatory with a wide band spectral response ranging from 3 keV up to 10 MeV energy band. This capability is supplemented by an unpreced…
The INTEGRAL high energy sky and the MeV-GeV connection
de Rosa, A.; Bird, A. J.; Ubertini, P. +5 more
After more than 6 years of operation, ESAs INTEGRAL Space Observatory has produced a wide number of results, ranging from the inventory of the high energy sources, depicting a gamma-ray sky populated by more than 700 high energy objects, to the discovery of the new class of Super Giant Fast X-ray Transient (SFXT) to dozens of variable galactic and…
The flaring blazars of the first 1.5 years of the AGILE mission
Antonelli, L. A.; Costa, E.; Mereghetti, S. +60 more
We report the AGILE γ-ray observations and the results of the multiwavelength campaigns on seven flaring blazars detected by the mission: During two multiwavelength campaigns, we observed γ-ray activity from two Flat Spectrum Radio Quasars of the Virgo region, e.g. 3C 279 and 3C 273 (the latter being the first extragalactic source simultaneously o…
INTEGRAL high energy sky: The keV to MeV cosmic sources
Ubertini, Pietro; Bazzano, Angela; Bassani, Loredana +2 more
After almost 5 years of operation, ESA's International Gamma-Ray Astrophysics Laboratory (INTEGRAL) Space Observatory has unveiled a new soft gamma-ray sky and produced a remarkable harvest of results, ranging from identification of new high energy sources, to the discovery of dozens of variable sources to the mapping of the aluminum emission from…
Imaging principles and techniques in space-borne gamma-ray astronomy
Schönfelder, Volker
Gamma-ray astronomy in the photon energy band from several 100keV up to say 10GeV can only be performed from space. Tremendous progress has been made in this young research field during the last 40 years. All-Sky maps exist now in continuum and line emission and short gamma-ray bursts-lasting only seconds-can be located to better than 1arcmin. The…
PICsIT: a position sensitive detector for space applications
Di Cocco, G.; Malaguti, G.; Schiavone, F. +8 more
Pixellated Imaging CsI Telescope (PICsIT) is the high energy detector plane of Imager on Board INTEGRAL Satellite (IBIS), one of the main instruments on board the International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite that will be launched in the year 2001. It consists of 4096 CsI(Tl) individual detector elements and operates in the …
