Ground Based Gamma-ray Astronomy
Michael Catanese
Abstract
Ground-based gamma-ray astronomy has come to be an important
complement to the Compton Gamma-Ray Observatory in the study of
high energy gamma-ray sources. Imaging atmospheric Cherenkov
telescopes are sensitive to cosmic sources which emit at energies
between ~ 200 GeV and 30 TeV, thus extending the reach of
CGRO in the study of the gamma-ray sky. They have huge effective
areas ( ~ 50,000 m2) for gamma-ray telescopes, permitting
sensitive studies of low flux sources and their short-term
variability. Ground-based studies of blazar-type active galactic
nuclei, pulsars and supernova remnants, particularly when combined
with lower energy observations, have aided our understanding of the
relativistic processes at work in these objects and the environments
around them. In this talk, I will review the observational status of
the field with particular emphasis on the developments that have
occurred since the 4th Compton Symposium.
