Title: TeV Astrophysics Abstract: Very high-energy gamma rays are created in some of the most extreme environments in the universe - supermassive black holes, merging neutron stars, and supernova remnants. These environments (and others) are now known to be efficient particle accelerators. Over the past decade our ability to detect these gamma rays and study cosmic particle accelerators has dramatically improved. Currently there are two different techniques used to detect very-high-energy (VHE) gamma rays. Imaging Atmospheric Cherenkov Telescopes detect the Cherenkov radiation generated in the atmosphere, while Extensive Air Shower Arrays detect the particles that reach the ground. In this talk I will discuss VHE gamma-ray astrophysics, the instruments used to detect TeV gamma rays, and the future outlook of the field.
