AGILE detection of extreme gamma-ray activity from the blazar PKS 1510-089 during March 2009. Multifrequency analysis
F. D'Ammando, C. M. Raiteri, M. Villata +112
We report on the extreme gamma-ray activity from the FSRQ PKS 1510-089 observed by AGILE in March 2009. In the same period a radio-to-optical monitoring of the source was provided…
INTEGRAL results on gamma-ray bursts and soft gamma-ray repeaters
Sandro Mereghetti
Despite not being specifically designed for the study of gamma-ray bursts (GRBs), the INTEGRAL satellite is giving a relevant contribution to this field with the detection of about…
Discovery of Powerful Gamma-Ray Flares from the Crab Nebula
M. Tavani, A. Bulgarelli, V. Vittorini +65
The well known Crab Nebula is at the center of the SN1054 supernova remnant. It consists of a rotationally-powered pulsar interacting with a surrounding nebula through a relativist…
The Twin Magnetars: SGR 1627-41 and 1E 1547-5408
S. Mereghetti, A. Tiengo, P. Esposito +10
We report on recent results obtained thanks to Target of Opportunity observations of the two galactic sources SGR 1627-41 and 1E 1547-5408. These two transient sources present seve…
Quiet but still bright: XMM-Newton observations of the soft gamma-ray repeater SGR 0526-66
A. Tiengo, P. Esposito, S. Mereghetti +6
SGR 0526-66 was the first soft gamma-ray repeater (SGR) from which a giant flare was detected in March 1979, suggesting the existence of magnetars, i.e. neutron stars powered by th…
Observation of GRBs with AGILE
M. Marisaldi, G. Barbiellini, E. Costa +21
Since its early phases of operation, the AGILE satellite is observing Gamma Ray Bursts (GRBs) over an energy range potentially spanning six orders of magnitude. In the hard X-ray b…
