Biography:
Barun obtained a B.Sc. (Hons.) in Physics from Scottish Church College, Kolkata, in 2016, and then an M.Sc. in Physics from University of Calcutta in 2018. He then joined NCRA-TIFR as a Research Scholar in July 2018, and completed the IUCAA-NCRA Graduate School in 2020. He is currently working on aspects of cosmic reionization with Tirthankar Roy Choudhury.
Research description:
According to the standard model of cosmology, the universe was mostly ionized and hot at very early stages. Then it cooled down with time and became predominantly neutral around 380,000 years after birth. Reionization is the era when the universe is again ionized by the photons coming from the first luminous sources. This is one of the least understood phases in the evolutionary history of the Universe and is also known as one of the final frontiers in modern cosmology. There are a handful of observational probes to explore the reionization era. My main research goal is to develop realistic and efficient models of reionization and subsequent epochs to understand the different
physical processes during that time. This will allow us to constrain reionization physics using available and upcoming observational data.
