The Department of Astronomy and Astrophysics is a part of the School of Natural Sciences of the Tata Institute of Fundamental Research.

The research interests of the Department are spread over a wide range of observational and theoretical areas. The department activity is broadly divided into three groups :

  • Theoretical Astrophysics: Study of the Sun, Supernovae, Neutron stars and Pulsars, Nucleosynthesis, Accretion disks around neutron stars and black holes, Cosmic star formation history, Gravitational Lensing and Cosmology, General Relativity and Gravitational Collapse, Dark Energy


  • Infrared and Optical Astronomy: Study of star formation in our Galaxy and other spiral galaxies; Structure and energetics of Galactic star forming regions through high angular resolution far infrared spectroscopic and photometric mapping; Radiative transfer in interstellar clouds; Infrared studies of circumstellar shells, young stellar objects and AGB stars; Study of interstellar medium using radio, sub-mm, infrared imaging and spectroscopy; Physics and Chemistry of Photon Dominated Regions (PDR); Study of the Galactic structure.


  • X-ray and Gamma ray Astronomy: Timing and spectral studies of Black Holes and Neutron star binaries, Cataclysmic variables, Nuclei of Active Galaxies and Quasars, X-ray spectroscopy of Stellar Coronae and Energetic phenomena on the Sun, Study of Hot Interstellar Medium and Supernova Remnants, Accretion disk - jet connection and origin of jets


The observations are carried out using ground based facilities as well as Balloon-borne and Satellite-borne instruments.

This is supplemented by the work done in Radio Astronomy and High Energy Cosmic Rays by other groups in the Institute.
