Abstract:
This paper provides a brief review of ground-based -ray Astronomy. It is intended to discuss the basic observational techniques, technological constraints, and the advantages of going down in threshold energy. Some of the major discoveries are listed --- galactic and extragalactic. We discuss some of the scientific returns as otained from observations of TeV sources such as the Crab nebula, shell remnants, and active galactic nuclei. Each source provides us with a richness of new physics, which prompt us to built larger telescopes and better photon detection devices to go down in threshold energy, so that ground-based observatories can overlap in energy with space observatories.- talk: Granada 1999/02/01
