TL;DR: In this article, the authors used the ground avoidance technique to estimate the spherically averaged 21 cm power spectra at the European Large Area ISO Survey-North 1 (ELAIS-N1) field.
Journal ArticleDOI
Characterizing EoR foregrounds: a study of the Lockman Hole region at 325 MHz
Aishrila Mazumder,Arnab Chakraborty,Abhirup Datta,Samir Choudhuri,Nirupam Roy,Yogesh Wadadekar,C. H. Ishwara-Chandra +6 more
TL;DR: In this paper, the angular power spectrum (APS) of the diffuse Galactic synchrotron emission is determined for three different Galactic latitudes using the tapered gridded estimator.
Journal ArticleDOI
Characterization of unresolved and unclassified sources detected in radio continuum surveys of the Galactic plane
Arnab Chakraborty,Nirupam Roy,Yu Wang,Abhirup Datta,Henrik Beuther,S.-N. X. Medina,Karl M. Menten,James Urquhart,Andreas Brunthaler,S. A. Dzib +9 more
TL;DR: In this paper, the authors study the Euclidean-normalized differential source counts of unclassified and unresolved sources detected in these surveys and compare them with simulated extragalactic radio source populations as well as previously established source counts.
