Shock geometry and inverse Compton emission from the wind of a binary pulsar (2000)
PSR B1259-63 is a 47ms radio pulsar with a high spin-down luminosity which is in a close, highly eccentric 3.5-year orbit about a bright stellar companion. The binary system may be a detectable...

We summarise the proceedings of the SRCfTA workshop on ``Supernova Remnants, Pulsars and the Interstellar Medium'' that was held at the University of Sydney on Mar 18 and 19, 1999.
Probing Pulsar Winds Using Inverse Compton Scattering (1999)
We investigate the effects of inverse Compton scattering by electrons and positrons in the unshocked winds of rotationally-powered binary pulsars. This process can scatter low energy target photons...

Electron Heating By The Cross-Shock Electric Potential (1998)
