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…
On the prospect of discovering `galaxy groups' through radio observations
Surajit Paul, Prateek Gupta, Reju Sam John +1
Observed steep mass scaling of radio power from the available high mass clusters has ruled out the prospect of detection of 'galaxy groups'. But, the available simulations and obse…
Manufacturing cosmic rays in the evolving dynamical states of galaxy clusters
Reju Sam John, Surajit Paul, Luigi Iapichino +2
Galaxy clusters are known to be reservoirs of Cosmic Rays (CRs), as inferred from theoretical calculations or detection of CR-derived observables. CR acceleration in clusters is mo…
Understanding `galaxy groups' as a unique structure in the universe
S. Paul, R. S. John, P. Gupta +1
`Galaxy groups' have hardly been realised as a separate class of objects with specific characteristics in the structural hierarchy. The presumption that the self-similarity of dark…
Clusters of galaxies and the cosmic web with SKA
Ruta Kale, K. S. Dwarakanath, Dharam Vir Lal +7
The intra-cluster and inter-galactic media (ICM, IGM) that pervade the large scale structure of the Universe are known to be magnetised at sub-micro Gauss to micro Gauss levels and…
Tracing the merger history of MACS clusters using the GMRT
S. Paul, A. Datta, H. T. Intema
Galaxy-cluster merger shocks efficiently accelerate the ambient electrons through diffusive shock acceleration and amplify magnetic field by compressing the Inter Cluster Medium. A…
