Demonstrating the Tapered Gridded Estimator (TGE) for the Cosmological HI 21-cm Power Spectrum using GMRT observations
Srijita Pal, Somnath Bharadwaj, Abhik Ghosh +1
We apply the Tapered Gridded Estimator (TGE) for estimating the cosmological 21-cm power spectrum from GMRT observations which corresponds to the neutral hydroge…
First multi-redshift limits on post-Epoch of Reionization (post-EoR) 21 cm signal from z = 1.96 - 3.58 using uGMRT
Arnab Chakraborty, Abhirup Datta, Nirupam Roy +8
Measurement of fluctuations in diffuse HI 21 cm background radiation from the post-reionization epoch (z < 6) is a promising avenue to probe the large-scale structure of the Univer…
Angular power spectrum of supernova remnants: effects of structure, geometry and diffuse foreground
Samir Choudhuri, Preetha Saha, Nirupam Roy +2
The study of the intensity fluctuation power spectrum of individual supernova remnants (SNRs) can reveal the structures present at sub-pc scales, and also constrain the physical pr…
Characterizing EoR foregrounds: A study of the Lockman Hole Region at 325 MHz
Aishrila Mazumder, Arnab Chakraborty, Abhirup Datta +4
One of the key science goals for the most sensitive telescopes, both current and upcoming, is the detection of the redshifted 21-cm signal from the Cosmic Dawn and Epoch of Reioniz…
All sky angular power spectrum: I. Estimating brightness temperature fluctuations using TGSS 150 MHz survey
Samir Choudhuri, Abhik Ghosh, Nirupam Roy +3
Measurements of the Galactic synchrotron emission is relevant for the 21-cm studies from the Epoch of Reionization. The study of the synchrotron emission is also useful to quantify…
