VERITAS, the Very Energetic Radiation Imaging Telescope Array System, is a TeV gamma-ray observatory located in Southern Arizona. VERITAS, which came online as a full array in Fall 2007, comprises four 12m-diameter imaging atmospheric Cherenkov telescopes. VERITAS features high sensitivity over a wide range of energies (from 100 GeV to > 30 TeV). This TeV observatory complements the Fermi Gamma-ray Space Telescope , which operates in the energy range 30 MeV - 300 GeV.

The VERITAS Group at Columbia Univeristy in New York is part of the VERITAS collaboration, which operates the most sensitive instrument for detecting TeV gamma-rays in the Northern Hemisphere. The VERITAS Group at Columbia University, led by Brian Humensky, consists of undergraduate students and graduate students from Columbia and post-doctoral research scientists. Together, we carry out scientific research with the VERITAS array on galactic and extragalactic sources in the various energy ranges from the GeV with Fermi to the TeV with VERITAS. We also collaborate very closely with the VERITAS group at Barnard College led by Reshmi Mukherjee
