AGILE detection of a gamma-ray re-brightening of the blazar PKS 1510-089
Abstract
The Flat Spectrum Radio Quasar PKS 1510-089, shows a new significant re-brightening above 100 MeV following the previous period of intense gamma-ray activity (see Pucella et al., ATel #1968; D'Ammando et al., ATel #1957). A maximum likelihood analysis of 1AGL J1511-0809 (PKS 1510-089) data obtained between 2009-03-18 05:45 UT and 2009-03-19 05:33 UT for photon energies above 100 MeV yields a detection significance of above 7 sigma with a source flux of about 400 x 10^-8 ph cm^-2 s^-1.
