New Directions in Gamma Ray Astronomy

Roger Blandford, KIPAC, Stanford

The recent successes in TeV astronomy associated with H.E.S.S., MAGIC and VERITAS together with the launch of AGILE and the anticipated launch of GLAST are ushering in the golden age of gamma ray astronomy. Gamma ray astronomy is a multi-wavelength and multi-messenger field and has especially strong connections with X-ray astronomy. The generic astrophysical and physical problems that should be elucidated by upcoming observations include particle acceleration and field amplification at collisionless shocks, fluid dynamical and microphysical properties of relativistic outflows, the electromagnetic properties of pulsar and black hole magnetospheres and the nature of dark matter.
