AGILE detection of prolonged and intense gamma-ray emission from Cygnus X-3
Abstract
After the recent gamma-ray detection (ATel #11804), AGILE is detecting a prolonged gamma-ray emission above 100 MeV from a source positionally consistent with the microquasar Cygnus X-3. A preliminary multi-source likelihood analysis detects a peak gamma-ray flux F( > 100 MeV) = (4.7 +/- 1.7) x 10^-6 photons/cm^2/s, integrating from 2018-07-02 UT 06:00:00 to 2018-07-04 UT 06:00:00.
