AGILE detection of delayed gamma-ray emission from GRB 080514B
A. Giuliani, S. Mereghetti, F. Fornari +55
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion…
IPN localizations of Konus short gamma-ray bursts
V. D. Pal'shin, K. Hurley, D. S. Svinkin +71
Between the launch of the \textit{GGS Wind} spacecraft in 1994 November and the end of 2010, the Konus-\textit{Wind} experiment detected 296 short-duration gamma-ray bursts (includ…
Search for gravitational waves associated with gamma-ray bursts detected by the InterPlanetary Network
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +901
We present the results of a search for gravitational waves associated with 223 gamma-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO's fifth…
Characterization of a tagged -ray beam line at the DANE Beam Test Facility
P. W. Cattaneo, A. Argan, F. Boffelli +64
At the core of the AGILE scientific instrument, designed to operate on a satellite, there is the Gamma Ray Imaging Detector (GRID) consisting of a Silicon Tracker (ST), a Cesium Io…
Multiwavelength observations of 3C 454.3. I. The AGILE 2007 November campaign on the "Crazy Diamond"
S. Vercellone, A. W. Chen, V. Vittorini +68
[Abridged] We report on a multiwavelength observation of the blazar 3C 454.3 (which we dubbed "crazy diamond") carried out on November 2007 by means of the astrophysical satellites…
