Astrophysics Seminar

Towards the Cosmological 21-cm Power spectrum using the Tapered Gridded Estimator

Speaker: Somnath Bharadwaj (Professor, IIT, Kharagpur)

Date and time
A&A Lecture Hall


The redshifted 21-cm signal is a very promising probe of Cosmology.  This talk will briefly review the subject of 21-cm Cosmology, and then present the Tapered Gridded Estimator for the 21-cm power spectrum.  This estimator has been applied to data from observations with the uGMRT and the  MWA. The talk will present the progress in the analysis of the data from these two observations.
