Abstract
We have continued our program to search for fast gamma ray pulsars (P<0.5 s) in OSSE observations of the galactic plane and selected other directions. We have used search strategies optimized for both isolated and binary pulsars. The large data sets and CPU requirements have been accommodated by performing the search on a 16k node CM‐200 parallel computer. Applied to OSSE observations, these techniques are sensitive to isolated Crab pulsars at the galactic center and binary Crab pulsars in the local spiral arms. We report on new pulsar searches in several galactic plane fields, as well as searches for pulsed gamma rays from SN1993J. No pulsations have been detected from either binary or isolated pulsars at frequencies between 2 Hz and 500 Hz with pulse fractions <0.2% and pulse fluxes <3×10−4 γ s−1 cm−2.
