PROFESSOR R. SRIANAND

Formation and evolution of galaxies is one of the main themes of research in physical cosmology. It is now well recognized that galaxy evolution is governed by various feedback processes such as infall and outflow of baryons, radiative feedback from meta-galactic UV background and AGN feedback from growing black holes in the centers of galaxies. While considerable progress is made in directly detecting high-z galaxies absorption line studies towards distant bright objects like quasars and GRBs are very useful to get handle on the physical processes that are driving the galaxy formation evolution. In this talk the speaker will provide a basic framework used, summarize recent results obtained in the field and provide a general picture that is emerging from these studies. The speaker will also outline various observing programmes with TMT that can provide next major jump in our understanding.
