AGILE gamma-ray detection of the Blazar 3C 454.3
Abstract
The AGILE satellite, currently in the science performance verification phase, started to observe the 3C454.3 field on July 24, 2007, following the significant flaring activity of this blazar recently detected in the optical and X-ray energy bands. A gamma-ray source positionally consistent with 3C 454.3 is detected with a maximum likelihood analysis giving a significance of 4.9 sigma in the AGILE GRID (Gamma-Ray Imaging Detector) data acquired between 2007-07-24 14:30 UT and 2007-07-27 05:27 UT.
