Evidence of sloshing-driven mini-halo formation in the cool-core cluster RXCJ1558.3-1410
Vishal S. Kale, Sonali K. Kadam, Sameer Salunkhe +6
Radio mini-halos are perplexing features, typically hosted by X-ray cool-core galaxy clusters. Understanding the connection between thermal X-ray and non-thermal radio emission is…
MeerKAT HI observations of Low Surface Brightness/Ultradiffuse Galaxy Candidates Projected around Two Southern Loose Groups
Chandreyee Sengupta, Tom C. Scott, Hao Chen +9
A large catalogue of low surface brightness galaxies (LSBGs) from the Dark Energy Survey showed significant clustering around nearby galaxy groups and clusters. Using the HIPASS su…
The radio halo in PLCKESZ G171.94 40.65: Beacon of merging activity
Ramananda Santra, Ruta Kale, Simona Giacintucci +6
We present the first multi-frequency analysis of the candidate ultra-steep spectrum radio halo in the galaxy cluster PLCKESZ G171.9440.65, using the upgraded Giant Metrewave Rad…
The prototypical major cluster merger Abell 754. I. Calibration of MeerKAT data and radio/X-ray spectral mapping of the cluster
A. Botteon, R. J. van Weeren, D. Eckert +6
Abell 754 is a rich galaxy cluster at and is considered the prototype of a major cluster merger. Like many dynamically unrelaxed systems, it hosts diffuse radio emission…
A Deep uGMRT view of the ultra steep spectrum radio halo in Abell 521
Ramananda Santra, Ruta Kale, Simona Giacintucci +8
We present the first detailed analysis of the ultra-steep spectrum radio halo in the merging galaxy cluster Abell 521, based on upgraded Giant Metrewave Radio telescope (uGMRT) obs…
Exploring diffuse radio emission in galaxy clusters and groups with the uGMRT and the SKA
Surajit Paul, Ruta Kale, Abhirup Datta +13
Diffuse radio emission has been detected in a considerable number of galaxy clusters and groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic par…
