AGILE detection of prolonged gamma-ray activity from the blazar PKS 1830-211
Abstract
The AGILE Gamma-Ray Imaging Detector (GRID) has been detecting prolonged gamma-ray emission above 100 MeV from a source at (l,b)=(12.17,-6.25) [RA(J2000)=18h 35m 44.07s, DEC(J2000)=-21h 18m 00.7s] positionally consistent with the high z blazar (z=2.507) PKS 1830-211.
Integrating from 2010-10-15 00:00UT to 2010-10-17 00:00UT, a quick-look maximum likelihood analysis yields a source flux of about (5.7+-1.8)E-6 ph/cm2/sec (E > 100 MeV).- Publication:
