Journal ArticleDOI
KAT-7 observations of an unbiased sample of mass-selected galaxy clusters
Gianni Bernardi,Gianni Bernardi,Tiziana Venturi,Rossella Cassano,Daniele Dallacasa,Gianfranco Brunetti,V. Cuciti,V. Cuciti,Melanie Johnston-Hollitt,Nadeem Oozeer,Nadeem Oozeer,Viral Parekh,Oleg Smirnov +12 more
TL;DR: In this paper, the authors present observations of 14 mass-selected galaxy clusters and test the correlation between the radio halo power at 1.4 GHz and the cluster mass, finding that radio halos in less massive galaxy clusters are statistically rare.
Journal ArticleDOI
A study of diffuse radio sources and X-ray emission in six massive clusters
TL;DR: In this paper, the authors used GMRT and EVLA radio observations of six galaxy clusters taken from the MAssive Cluster Survey (MACS) catalogue to detect diffuse radio emission.
Journal ArticleDOI
How unusual is the cool-core radio halo cluster CL1821+643?
Ruta Kale,Viral Parekh +1 more
TL;DR: In this paper, the radio halo of the cool core galaxy cluster CL1821+643 was analyzed using new radio observations and morphological analysis of its intra-cluster medium.
Journal ArticleDOI

TL;DR: In this article, the authors report on the discovery of a unique shock in a cluster pair 1E 2216.0-0401 and 1E´2215.7-0404.
Journal ArticleDOI
Twin radio relics in the nearby low-mass galaxy cluster Abell 168
TL;DR: In this paper, the authors reported the discovery of twin radio relics in the outskirts of the low-mass merging galaxy cluster Abell 168 (redshift=0.045) in which one of the relics is elongated with a linear extent, a projected width of 80 kpc and is located toward the north of the cluster center, oriented roughly perpendicular to the major axis of the X-ray emission.
