Cygnus X-3 revisited: 10 years of muon and radio observations.

Conference ·
OSTI ID:11871
The Soudan 2 deep underground tracking calorimeter has recorded cosmic ray muon tracks from the direction of the galactic x-ray binary Cygnus X-3 on most transits during the interval 1989-1998. We analyze these events in the context of previous reports of Cygnus X-3-related muon flux during major radio flares of that source. We find some evidence for excess flux during a small number of transits coincident with major radio flares. We also find an indication that these events maybe distributed around the source with a Gaussian point spread function with {sigma} = 1.3{degree}, larger than the instrumental angular spread of < 0.3{degree}, verified by observation of the shadow of the moon.
