Description:
The prospects for obtaining evidence of the particle acceleration by SN 1987A pulsar wind are discussed. It is noted that, of the seven experiments that searched for high-energy signals since the discovery of SN 1987A, operating in both the TeV region (air Cerenkov arrays) and the 100-TeV region (air shower arrays), not one has reported a continuous signal from the supernova. The only signal reported so far that could be interpreted as a signal from the supernova remnant is from an air shower experiment YANZOS (Bond, 1988), in which a transient flux of photons above 3 TeV was observed. It is pointed out however, that, if a TeV signal is seen, the accompanying gamma-ray flux around 100 MeV should be well above threshold for detection by the EGRET detector on Gamma-Ray Observatory.
