Welcome to the Mukherjee group at Barnard College and Columbia University.
VERITAS, the Very Energetic Radiation Imaging Telescope Array System, is a TeV gamma-ray observatory located in Southern Arizona composed of four 12m-diameter imaging atmospheric Cherenkov telescopes. VERITAS came online as a full array in Fall 2007, and features high sensitivity over a wide range of energies (from 100 GeV to over 30 TeV). This TeV observatory effectively complements the Fermi Gamma-ray Space Telescope.
The VERITAS Group at Barnard College and Columbia University 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 Barnard College, led by Reshmi Mukherjee, consists of undergraduate students from Barnard, graduate students from Columbia, and post-doctoral research scientists. The Barnard Group is affiliated with Nevis Labs and Columbia University. We carry out scientific research on galactic and extragalactic sources in the GeV and TeV energy bands with data collected from Fermi and VERITAS.
We are actively involved in the development of the next-generation ground-based gamma-ray observatory, the Cherenkov Telescope Array (CTA). Together with the CTA-U.S. members and CTA-INFN groups in Italy, we are involved in the upgrade activities of the prototype Schwarzschild-Couder Telescope, the first of its kind featuring a dual-mirror design for superior imaging resolution.
