A measurement of Galactic synchrotron emission using MWA drift scan observations
Suman Chatterjee, Shouvik Sarkar, Samir Choudhuri +4
Studying the diffuse Galactic synchrotron emission (hereafter, DGSE) at arc-minute angular scale is important to remove the foregrounds for the cosmological 21-cm observations. Sta…

The Tracking Tapered Gridded Estimator for the 21-cm power spectrum from MWA drift scan observations II: The Missing Frequency Channels
Khandakar Md Asif Elahi, Somnath Bharadwaj, Suman Chatterjee +4
Missing frequency channels pose a problem for estimating the redshifted 21-cm power spectrum (PS) from radio-interferometric visibility data. This is parti…
