Astrophysics and Cosmology

About Us

The astrophysics and Cosmology group is involved in research at all length scales from the Solar System to cosmological distances. We use observations at all wavelengths from radio to gamma-rays and also non-EM windows such as neutrinos and gravitational waves. The main focus areas include solar corona and wind, black holes, micro-quasars, active galactic nuclei, pulsars, gamma-ray bursts, space plasmas, dark matter and dark energy, galaxy clusters and groups, Cosmic Microwave Background. For this purpose, we use state of the art national and international facilities such as AstroSat, GMRT, Swift, Liverpool telescope, e-MERLIN, DECam, Fermi, South Pole Telescope, and are also part of international collaborations such as Dark Energy Survey, International Pulsar Timing array consortium. We also have a dedicated in-house optical telescope on campus which is regularly used for observations. Since Astronomy has become a data intensive science, a lot of our research is done on High performance computers and involves novel data mining and Machine learning techniques.
