TeV gamma ray observations of Shell-type Supernova remnants by the CAT telescope (1999-2001)
Abstract
The recent evidence of TeV γ-ray emission from the Supernova Remnant (SNR) Cassiopeia A (Aharonian et al., 2001) demonstrates the interesting nature of these sources as candidate accelerators of cosmic rays. The observed TeV γ-ray emission may be produced by high-energy electrons and/or nuclei accelerated by shock fronts within the SNR. Here we report on observations by the CAT imaging Cherenkov telescope on the SNRs CTA 1 and IC443 during the years 2000-01. We also present our observations of the plerion CTB 80 during the same period. Gamma-ray flux upper limits are given for positions coincident with EGRET detections of each source.
