OVERVIEW OF TEV GAMMA-RAY OBSERVATIONS

TeV emission has been observed with high signal-to-noise from: two pul sar-driven supernova remnants, the Crab Nebula and PSR B1706-44 and a blazar class AGN, Markarian 421. Other sources, observed without the b enefit of major background reduction techniques, are some of the compa ct object binaries. These discoveries plus the discoveries of EGRET of more than 130 sources at lower energies point to a growing number of scientific questions capable of being addressed by this field (particu larly for distant sources via intergalactic absorption processes). Rap id further development will come as new instruments employing a variet y of background reduction techniques come on-line.
