10 Apr 2013 | | Abstract: | We have reanalysed the giant outburst of the blazar PKS 1510-089 (z=0.36)
occurred on 2011 October-November. The gamma-ray flux in the 0.1-100 GeV energy
range exceeded the value of 10^-5 ph/cm2/s for several days. The peak flux was
reached on 2011 October 19, with a value of 4.4 x 10^-5 ph/cm2/s, which in turn
corresponds to a luminosity of 2 x 10^49 erg/s. Very short time scale
variability was measured. Particularly, on 2011 October 18, the flux doubling
time was as small as 20 minutes. This is the shortest variability ever detected
in the MeV-GeV energy band. We compared the present analysis with two other
outbursts observed in 2009 March and 2012 February-March, when the blazar was
detected also by HESS and MAGIC, respectively, in order to infer information
about the emission at hundreds of GeV. | | Source: | arXiv, 1304.2878 | | Services: | Forum | Review | PDF | Favorites | |
