What is VERITAS?

VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a ground-based observatory for gamma-ray astronomy in the energy range 50 GeV- 50 TeV. It is an array of four 12m optical reflectors, used to record Cherenkov radiation created by high-energy gamma-ray showers in the atmosphere.

VERITAS is the most sensitive atmospheric Cherenkov telescope in the northern hemisphere. Critical measurements of astrophysical sources such as active galactic nuclei, supernova remnants, pulsars, and gamma-ray bursts are made. In addition, VERITAS probes beyond the standard models of particle physics and cosmology by searching for dark matter, primordial black holes and violation of Lorentz invariance. These measurements complement Fermi, the next generation satellite telescope that was launched in 2008.
