MOSS III: MeerKATs view on the galaxy populations in two massive galaxy clusters
Robert Kincaid, Mark Sargent, Pascale Jablonka +5
The MeerKAT Observations of the Saraswati Supercluster (MOSS) is an ongoing project attempting to study the radio and optical properties of the core region of the Saraswati supercl…
uGMRT and MeerKAT observation of RXCJ0232-4420: a quiet cluster with a giant radio halo
Pralay Biswas, Ramananda Santra, Ruta Kale +1
Giant radio halos are the Mpc-scale extended sources associated with the merging clusters, while the mini-halos are preferentially associated with cool-core clusters. Both trace th…
What drives the wheels of evolution in NGC 1512? A UVIT study
Thomas Robin, Sreeja S Kartha, Ujjwal Krishnan +4
Environmental and secular processes play a pivotal role in the evolution of galaxies. These can be due to external processes such as interactions or internal processes due to the a…
Mining Mini-Halos with MeerKAT I. Calibration and Imaging
K. S. Trehaeven, V. Parekh, N. Oozeer +7
Radio mini-halos are clouds of diffuse, low surface brightness synchrotron emission that surround the Brightest Cluster Galaxy (BCG) in massive cool-core galaxy clusters. In this p…
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…
Jets from MRC 0600-399 bent by magnetic fields in the cluster Abell 3376
James O. Chibueze, Haruka Sakemi, Takumi Ohmura +7
Galaxy clusters are known to harbour magnetic fields. The nature of the intra-cluster magnetic fields remains an unresolved question. Intra-cluster magnetic field can be observed a…
A MeerKAT view on galaxy clusters: a radio-optical study of Abell 1300 and MACS J1931.8--2634
B. Terni de Gregory, B. Hugo, T. Venturi +8
In this paper we present results from a radio-optical study of the galaxy populations of the galaxy clusters Abell 1300 and MACS J1931.82634, a merger and a relaxed system respe…
MeerKAT's discovery of a radio relic in the bimodal merging cluster A2384
V. Parekh, K. Thorat, R. Kale +12
We present the discovery of a single radio relic located at the edge of the galaxy cluster A2384, using the MeerKAT radio telescope. A2384 is a nearby ( = 0.092), low mass, comp…
AGN Feedback in galaxy groups: a detailed study of X-ray features and diffuse radio emission in IC1262
M. B. Pandge, S. S. Sonkamble, Viral Parekh +4
This paper reports a systematic search of X-ray cavities, density jumps and shocks in the inter-galactic environment of the galaxy group IC~1262 using {\it Chandra}, GMRT and VLA a…
A study of spectral curvature in the radio relic in Abell 4038 using the uGMRT
Ruta Kale, Viral Parekh, K. S. Dwarakanath
The remnant radio galaxies in galaxy clusters are important sources of seed relativistic electron population in the intra-cluster medium (ICM). Their occurrence and spectral proper…
A hot X-ray filament associated with A3017 galaxy cluster
Viral Parekh, F. Durret, P. Padmanabh +1
Recent simulations and observations have shown large scale filaments in the cosmic web connecting nodes, with accreting materials (baryonic and dark matter) flowing through them. C…
A study of diffuse radio sources and X-ray emission in six massive clusters
Viral Parekh, K. S. Dwarakanath, Ruta Kale +1
The goal of the present study is to extend our current knowledge of the diffuse radio source (halo and relic) populations to 0.3. Here we report GMRT and EVLA radio observa…
