All-sky angular power spectrum – I. Estimating brightness temperature fluctuations using the 150-MHz TGSS survey
Ghosh, Abhik; Choudhuri, Samir; Roy, Nirupam (Oxford University Press, 2020)Measurements of the Galactic synchrotron emission are important for the 21-cm studies of the epoch of reionization. The study of synchrotron emission is also useful for quantifying the fluctuations in the magnetic field ... -
Foreground modelling via Gaussian process regression: an application to HERA data
Ghosh, Abhik; Mertens, Florent; Bernardi, Gianni (Oxford University Press, 2020)The key challenge in the observation of the redshifted 21-cm signal from cosmic reionization is its separation from the much brighter foreground emission. Such separation relies on the different spectral properties of the ...
