![]() | Kieda, David B. | High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1 | We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source.

![]() | Sokolsky, Pierre | Search for compact sources of cosmic photons above 200 TeV | From April 1988 to February 1990 we used a two-level array of scintillators to search in the cosmic radiation for compact sources of y rays above 200 TeV. Counters on the surface measured the size and direction of extensive air showers while counters buried 3 m below ground measured their muon conte... | Extensive air showers; Cygnus X-3; Hercules X-1; Crab Nebula; Ultrahigh energies | 1992-10 |
