Understanding the Nature of the Ultra-Steep Spectrum Diffuse Radio Source in the Galaxy Cluster Abell 272
Arthur Whyley, Scott W. Randall, Tracy E. Clarke +7
Ultra-steep spectrum (USS) radio sources with complex filamentary morphologies are a poorly understood subclass of diffuse radio source found in galaxy clusters. They are character…
Deep Chandra observations of merging galaxy cluster ZwCl 2341+0000
X. Zhang, A. Simionescu, C. Stuardi +9
Knowledge of X-ray shock and radio relic connection in merging galaxy clusters has been greatly extended in terms of both observation and theory over the last decade. ZwCl 2341+000…
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…
Revived Fossil Plasma Sources in Galaxy Clusters
S. Mandal, H. T. Intema, R. J. van Weeren +10
It is well established that particle acceleration by shocks and turbulence in the intra-cluster medium can produce cluster-scale synchrotron emitting sources. However, the detailed…
Detailed study of ELAIS N1 field with the uGMRT -- II. Source Properties and Spectral Variation Of Foreground Power Spectrum from 300-500 MHz Observations
Arnab Chakraborty, Nirupam Roy, Abhirup Datta +8
Understanding the low-frequency radio sky in depth is necessary to subtract foregrounds in order to detect the redshifted 21 cm signal of neutral hydrogen from the Cosmic Dawn, Epo…
Detailed study of the ELAIS N1 field with the uGMRT - I. Characterizing the 325 MHz foreground for redshifted 21 cm observations
Arnab Chakraborty, Abhirup Datta, Samir Choudhuri +8
In this first paper of the series, we present initial results of newly upgraded Giant Meterwave Radio Telescope (uGMRT) observation of European Large-Area ISO Survey-North 1 (ELAIS…
