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…
Searching for high-z radio galaxies with the MGCLS
Kenda Knowles, Sinah M. Manaka, Michael F. Bietenholz +5
We present results from a search for high-redshift radio galaxy (HRG) candidates using 1.28 GHz data in the Abell 2751 field drawn from the MeerKAT Galaxy Cluster Legacy Survey…
The MeerKAT Galaxy Cluster Legacy Survey I. Survey Overview and Highlights
K. Knowles, W. D. Cotton, L. Rudnick +148
MeerKAT's large number of antennas, spanning 8 km with a densely packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity over a wide range of an…
A Multiwavelength Dynamical State Analysis of ACT-CL J0019.6+0336
Denisha S. Pillay, David J. Turner, Matt Hilton +8
In our study, we show a multiwavelength view of ACT-CL J0019.6+0336 (which hosts a radio halo), to investigate the cluster dynamics, morphology, and ICM. We use a combination of XM…
MeerKAT view of the diffuse radio sources in Abell 3667 and their interactions with the thermal plasma
F. de Gasperin, L. Rudnick, A. Finoguenov +11
During their lifetime, galaxy clusters grow through the accretion of matter from the filaments of the large scale structure and from mergers with other clusters. These mergers rele…
One Source, Two Source(s): Ribs and Tethers
Lawrence Rudnick, William Cotton, Kenda Knowles +1
We present the unique and challenging case of a radio galaxy in Abell 3266 observed as part of the MeerKAT Galaxy Cluster Legacy Survey. It has quasi-periodic bright patches along…
