Intensity fluctuations of radio halo in galaxy cluster: Insights from power spectrum estimation
Srijita Pal, Nirupam Roy, Sameer Salunkhe +3
Non-thermal synchrotron emissions from radio halo allow us to study mechanisms of particle (re)acceleration, magnetic field distribution, merger history, and turbulence in the intr…
The Large-Scale Structure of the Universe through the SKA lenses
Virginia Cuciti, Surajit Paul, Viral Parekh +11
The large-scale distribution of galaxies in the Universe forms an intricate, interconnected network known as the cosmic web. Cosmological simulations within the standard Lambda-CDM…
MOSS II: Mid frequency radio catalog of Saraswati core region
Robert Kincaid, Edwin Retana-Montenegro, Bruno Slaus +6
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…
Combined LOFAR-uGMRT analysis of the diffuse radio emission in the massive clusters Abell 773 and Abell 1351
K. S. L. Srikanth, A. Botteon, R. Cassano +20
Radio halos are megaparsec-scale diffuse, non-thermal radio sources located at the centers of galaxy clusters, tracing relativistic particles and magnetic fields in the intra-clust…
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…
Discovery of a radio megahalo in the cluster PLCKG287.0+32.9 using the uGMRT
Sameer Salunkhe, Ramananda Santra, Ruta Kale
We report the discovery of a radio megahalo in the merging cluster PLCKG287.0+32.9, based on upgraded Giant Metrewave Radio telescope (uGMRT) observations at frequencies 300-850 MH…
