56Co gamma-rays from SN1998bu: COMPTEL upper limits
S. Plueschke, R. Georgii, R. Diehl +7
The type Ia supernova SN1998bu in M96 was observed by COMPTEL for a total of 88 days starting 17 days after the first detection of the supernova. The accumulated effective observat…
The Comptel 1.809 Mev Survey
S. Plueschke, R. Diehl, V. Schoenfelder +8
We present the latest update of the 1.809 MeV sky survey obtained with COMPTEL. Based on all observations taken since the launch of CGRO in spring 1991 to early summer this year we…
Evidence for TeV Emission from GRB 970417a
The Milagro Collaboration, R. Atkins, W. Benbow +37
Milagrito, a detector sensitive to very high energy gamma rays, monitored the northern sky from February 1997 through May 1998. With a large field of view and a high duty cycle, th…
Instrumented Water Tanks can Improve Air Shower Detector Sensitivity
R. Atkins, W. Benbow, D. Berley +40
Previous works have shown that water Cherenkov detectors have superior sensitivity to those of scintillation counters as applied to detecting extensive air showers (EAS). This is i…
Calibration of the Milagro Cosmic Ray Telescope
R. Atkins, W. Benbow, D. Berley +40
The Milagro detector is an air shower array which uses the water Cherenkov technique and is capable of continuously monitoring the sky at energies near 1 TeV. The detector consists…
Study of the Shadows of the Moon and the Sun with VHE Cosmic Rays
R. Atkins, W. Benbow, D. Berley +40
Milagrito, a prototype for the Milagro detector, operated for 15 months in 1997-8 and collected 8.9 billion events. It was the first extensive air shower (EAS) array sensitive to s…
