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…
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…
