Constraints on cosmic-ray observation of Cygnus X-3Two experimental groups working at different minimum energies have reported underground muons coming from the direction of Cygnus X-3 with rates that vary in synchrony with its binary period. At the Mont Blanc detector the events are, within statistics, uniformly spread over a 5 degree circle around the position of Cygnus X-3, even though the angular resolution is significantly better than this. The ratio of events in the phase peak to total muons observed rises as a function of minimum muon energy. An experiment also sees an excess in the number of pairs of codirectional multiple muon events arriving within about 5000 seconds of each other, the excess events coming from a direction about 20 degrees away from Cygnus X-3.
