Dr. Ashish Raj

Assistant Professor-II

I specialize in studying transient sources such as CVs, supernovae, gamma-ray bursts, neutron star mergers, tidal disruption events, AGN flares, and early type stars. My research focuses on understanding their characteristics, spectral evolution, molecule and dust formation processes, and investigating the physical properties of the underlying systems. Additionally, I investigate the presence of dust around low-luminosity early-type stars through high-resolution spectroscopic observations, aiming to solve the puzzle of large amounts of circumstellar matter near these stars.

Greetings, I am Ashish Raj, currently serving as an Assistant Professor at the Indian Centre for Space Physics (ICSP) in Kolkata. I proudly hold a Life Membership with the Astronomical Society of India and am also an individual member of the International Astronomical Union (IAU). Furthermore, I have previously been a member of the Korean Astronomical Society. My primary focus of research lies in the exploration of transient sources, early type stars, and star clusters. It is my passion and dedication to unravel the mysteries of these celestial phenomena that drives my work in the field of astronomy.
