AGILE detection of enhanced gamma-ray activity from the FSRQ PKS 1830-211
Abstract
AGILE is detecting enhanced gamma-ray activity above 100 MeV from the blazar PKS 1830-211 (also known as 5BZQ J1833-2103). Integrating from 2019-02-27 UT 06:00:00 until 2019-03-01 06:00:00, a preliminary multi-source maximum likelihood analysis yields a detection at the level of about 5.5 sigma and a flux F( > 100 MeV) = (3.1 +/- 0.8) x 10^-6 photons/cm^2/s, at Galactic coordinates (l, b) =(12.2, -5.7) +/- 0.6 deg (95% stat.
