A GMRT Narrowband vs. Wideband Analysis of the ACT-CLJ0034.4+0225 Field Selected from the ACTPol Cluster Sample
Sinenhlanhla P. Sikhosana, Kenda Knowles, C. H. Ishwara-Chandra +3
Low frequency radio observations of galaxy clusters are a useful probe of the non-thermal intracluster medium (ICM), through observations of diffuse radio emission such as radio ha…
Why are some galaxy clusters underluminous? The very low concentration of the CL2015 mass profile
S. Andreon, A. Moretti, G. Trinchieri +1
Our knowledge of the variety of galaxy clusters has been increasing in the last few years thanks to our progress in understanding the severity of selection effects on samples. To u…
153 MHz GMRT follow-up of steep-spectrum diffuse emission in galaxy clusters
G. Macario, T. Venturi, H. T. Intema +7
In this paper we present new high sensitivity 153 MHz Giant Meterwave Radio Telescope follow-up observations of the diffuse steep spectrum cluster radio sources in the galaxy clust…
Radio continuum emission and HI gas accretion in the NGC 5903/5898 compact group of early-type galaxies
Gopal-Krishna, Mukul Mhaskey, Paul J. Wiita +3
We discuss the nature of the multi-component radio continuum and HI emission associated with the nearby galaxy group comprised of two dominant ellipticals, NGC 5898 and NGC 5903, a…
Deep GMRT 150 MHz observations of the DEEP2 fields: Searching for High Red-shift Radio Galaxies Revisited
Susanta Kumar Bisoi, C. H. Ishwara-Chandra, S. K. Sirothia +1
High red-shift radio galaxies are best searched at low radio frequencies, due to its steep radio spectra. Here we present preliminary results from our programme to search for high…
Discovery of the first giant double radio relic in a galaxy cluster found in the PLANCK Sunyaev-Zel'dovich cluster survey: PLCK G287.0+32.9
Joydeep Bagchi, S. K. Sirothia, Norbert Werner +6
We report the discovery of large scale diffuse non-thermal radio emission in PLCK G287.0+32.9, an exceptionally hot (T ~ 13 keV), massive and luminous galaxy cluster, strongly dete…
