Modeling reionization history of the Universe

Dr. Sourav Mitra

Surendranath College, Kolkata

Reionization is a complex process whereby hydrogen (and helium) in the Universe is ionized by the radiation from first luminous sources. Theoretically, the importance of the reionization lies in its close coupling with the formation of first cosmic structures. Also observationally, the reionization era represents a phase of the Universe which is yet to be probed and hence, over the past few years, there has been considerable effort made in modeling the process. In this talk, I will try to discuss the basic physics behind cosmological reionization along with its various observational constraints and their current status.
