Biography and Research Information
OverviewAI-generated summary
Arnab Sarkar's research focuses on the physics of cosmic ecosystems, particularly investigating the composition and behavior of the circumgalactic medium and intergalactic gas. His work utilizes observational data from astronomical instruments to study phenomena such as X-ray line emission from hot gas, chemical abundances in galaxy groups, and the effects of supermassive black hole feedback. Sarkar has published on topics including improved models for emission lines in active galactic nuclei (AGNs) and the mass-metallicity relation of galaxies at high redshifts. He also studies shock phenomena in intercluster filaments. His recent publications include work on the "Cloudy" code, the Line Emission Mapper (LEM), and the analysis of X-ray metal line emission. Sarkar has an h-index of 11 and over 530 citations across his 65 publications. He has collaborated with Priyanka Chakraborty on 25 shared publications.
