Transient Gamma-ray Emission from Cygnus X-3 Detected by AGILE : Leptonic and Hadronic Emission Models

Abstract

The AGILE satellite detected several episodes of transient γ-ray emission from Cygnus X-3. Cross-correlating the AGILE light curve with both X-ray and radio monitoring data, we found that the main events of γ-ray activity were detected while the system was in soft spectral X-ray states, that coincide with local and often sharp minima of the hard X-ray flux… (More)
