Pulsars, Pulsar Winds and Plerions

Abstract

Rotation-powered pulsars and the interaction with their environments are expected sources of high-energy gamma-ray emission. I will discuss the latest developments in models for pulsed emission, including the slot gap extension of the polar cap model and outer gap models, and the predicted emission at GeV and TeV energies. Millisecond pulsars appear to be especially promising sources at energies around 50- 100 GeV. There have also been a number of new plerions discovered in the X-ray band over the last few years by Chandra and XMM. I will review these observations as well as the models for high-energy emission from these sources.
