High Energy Non-thermal Astrophysics

The acceleration of particles in a wide range of galactic and extragalactic objects leads to non-thermal particle energy distributions and associated very broad-band emission. Recent advances in the imaging atmospheric Cherenkov technique, as demonstrated in particular by the HESS, MAGIC and VERITAS collaborations, have opened up a new observational window for ground-based astronomy at TeV gamma-ray energies. Together with the very exciting first results from the Fermi gamma-ray space telescope at GeV energies, as well as observations by Fermi and other space missions at MeV energies, gamma-ray astronomy now offers a new perspective on the high-energy non-thermal universe at photon energies from MeV to TeV.

This session will highlight recent experimental results, plans for future instruments, complementary studies of high-energy gamma-ray sources at other wavelengths, and links to neutrino astrophysics and cosmic-ray studies as well as theoretical and phenomenological work on the processes responsible for the high-energy emission.
