Gamma-ray flaring emission from Cygnus X-3 detected by AGILE
Abstract
AGILE continues to detect gamma-ray flaring emission from a source positionally consistent with the microquasar Cygnus X-3. Integrating during the period 2011-02-06 05:00 UT to 2011-02-08 09:00 UT (MJD= 55598.21-55600.37) the AGILE-GRID multi-source likelihood analysis finds enhanced gamma-ray emission above 100 MeV from a source at Galactic coordinates (l,b) = (79.46, 0.6) ± 0.7 (stat.) ± 0.1 (syst.) deg, (R.A.,Dec.) J2000 = (307.91, 40.58) deg, with flux F > 250 e-8 ph/cm2/sec for a 4.8 sigma significance.
