EGRET Observations of High-Energy Gamma Rays from Geminga
Abstract
The EGRET high-energy gamma ray telescope on the Compton Gamma Ray Observatory satellite (CGRO) observed the gamma-ray pulsar Geminga three times in 1991 and five times (albeit with low sensitivity) in 1992. A new ephemeris has been derived, based on the EGRET data alone. Phase-resolved spectra for the 30-10000 MeV energy range have been derived for the two peaks, the interpulse interval, and the ``extrapulse'' interval.
