Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
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…
The magnetic mayhem in Abell 2199: discovery of synchrotron threads and homogeneous diffuse radio lobes
R. Timmerman, L. Rudnick, A. Botteon +2
Sensitive low-frequency radio observations have started uncovering examples of synchrotron-emitting threads, isolated from the rest of radio emission in galaxy clusters. As the bri…
Probing High-redshift Intracluster Medium Using SKA
Ramananda Santra, Ruta Kale
Galaxy clusters host vast reservoirs of magnetised plasma in their intracluster medium (ICM), where turbulence and shocks generated during structure formation sometimes give rise t…
Probing Merger Shocks in Galaxy Clusters in the SKA Era
Arpan Pal, Ruta Kale, Gabriella Di Gennaro +8
Galaxy cluster mergers represent the most energetic phenomena in the Universe since the Big Bang releasing gravitational potential energy of erg, injecting turbul…
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…
XGAP with uGMRT I: Old AGN plasma in merging galaxy groups
R. Santra, R. Kale, K. Kolokythas +10
Galaxy groups are affected by outflows from central Active Galactic Nuclei due to the shallower gravitational potential compared to galaxy clusters. The group binding energy is com…
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…
Deep insights into Abell 2163: unveiling the treasure trove of ICM plasma physics
Ramananda Santra, Ruta Kale, Simona Giacintucci +4
Nonthermal emission observed in galaxy clusters provides a direct probe into the plasma physics of the intra-cluster medium (ICM) under extreme conditions. We report the first deta…
The Peculiar Mini-Halo in the Shapley Supercluster Member Abell 3558
K. S. Trehaeven, T. Venturi, O. Smirnov +9
We present a multi-band study of the diffuse emission in the galaxy cluster Abell 3558, located in the core of the Shapley Supercluster. Using new MeerKAT UHF-Band and uGMRT Band-3…
Extreme AGN feedback in the fossil galaxy group SDSSTG 4436
D. Eckert, F. Gastaldello, L. Lovisari +20
Supermassive black hole feedback is the currently favoured mechanism to regulate the star formation rate of galaxies and prevent the formation of ultra-massive galaxies ($M_\star>1…
Double radio relics and radio halo in the high redshift galaxy cluster El Gordo with the Upgraded GMRT
R. Kale, A. Botteon, D. Eckert +5
Diffuse synchrotron radio sources associated with the intra-cluster medium of galaxy clusters are of special interest at high redshifts to understand the magnetization and particle…
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…
A shock in `El Gordo' cluster and the origin of the radio relic
A. Botteon, F. Gastaldello, G. Brunetti +1
We present an X-ray and radio study of the famous `El Gordo', a massive and distant () galaxy cluster. In the deep (340 ks) Chandra observation, the cluster appears with an…
On the occurrence of Radio Halos in galaxy clusters - Insight from a mass-selected sample
V. Cuciti, R. Cassano, G. Brunetti +4
Giant radio halos (RH) are diffuse Mpc-scale synchrotron sources detected in a fraction of massive and merging galaxy clusters. An unbiased study of the statistical properties of R…
