VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a new major ground-based gamma-ray observatory with an array of four 12m optical reflectors for gamma-ray astronomy in the GeV - TeV energy range . The telescope design is based on the design of the existing 10m gamma-ray telescope of the Whipple Observatory. It consists of an array of imaging telescopes deployed such that they permit the maximum versatility and give the highest sensitivity in the 50 GeV - 50 TeV band (with maximum sensitivity from 100 GeV to 10 TeV). This VHE observatory will effectively complement Fermi.  Check out the VERITAS Sensitivity page for the most up to date infomation on VERITAS or review our our Recent Results section.
