Epoch of Reionization
PI: Abhirup Datta

The research in this group includes cosmological observations at low radio frequency with uGMRT, VLA, ATCA and in future SKA. Dr. Datta is a science team board member for Epoch of Reionization key science project in International SKA collaboration from India. His current interest in this field is in foreground characterization and removal from reionization data from radio interferometers using machine learning techniques like neural networks. This group is also working on using the state-of-the-art radio imaging/calibration algorithms to achieve high dynamic range imaging with low-frequency radio data-sets.

Dr. Datta is also collaborator in the international DARE (Dark Ages Radio Explorer) experiment which is currently a concept mission being proposed to NASA for flight. This involves probing cosmic reionization using the global 21cm signal. Currently, three PhD students are working in this area.
