Welcome to HAGAR Group

HAGAR, an array of seven telescopes, is operational at Hanle, Ladakh since September 2008. It is operated jointly by Tata Institute of Fundamental Research, Mumbai and Indian Institute of Astrophysics, Bengaluru. It is designed to study very high energy gamma ray emission from celestial objects. Gamma rays are detected indirectly using atmospheric Cherenkov technique. Prime targets include Active Galactic Nuclie (AGNs) and gamma ray pulsars. We aim to study emission regions and processes responsible for gamma ray production in these sources. Study of gamma ray emission is expected to shed some light on long standing puzzle regarding origin of cosmic rays. Also there are possibilities such as study of physics beyond standard model through dark matter searches, fundamental physics aspects like tests for Lorentz invariance violation as well as cosmological aspects like indirect estimation of extragalactic background light.
