A new enigmatic radio relic in the low mass cluster Abell 2108
Swarna Chatterjee, Majidul Rahaman, Abhirup Datta +2
We report the discovery of a radio relic in the northeastern periphery of the cluster Abell 2108 (A2108). A2108 is a part of the uGMRT LOw-MAss Galaxy Cluster Survey (GLOMACS), whe…
A Multi-Frequency View of the Radio Phoenix in the Abell 85 Cluster
Ramij Raja, Majidul Rahaman, Abhirup Datta +1
Radio phoenices are complex and filamentary diffuse radio sources found in both merging and relaxed clusters. The formation of these sources was proposed to be due to adiabatic com…
A radio bridge connecting the minihalo and phoenix in the Abell 85 cluster
Ramij Raja, Majidul Rahaman, Abhirup Datta +1
Galaxy clusters are located at the nodes of cosmic filaments and therefore host a lot of hydrodynamical activity. However, cool core clusters are considered to be relatively relaxe…
On the detection of multiple shock fronts in A1914 using deep Chandra X-ray observations
Majidul Rahaman, Ramij Raja, Abhirup Datta
Here, we report the new detection of three shock fronts using archival \textit{Chandra} X-ray observations in Abell 1914, which also hosts a radio halo, a radio phoenix, and a head…
An X-ray and Radio Study of the Hubble Frontier Field Cluster Abell S1063
Majidul Rahaman, Ramij Raja, Abhirup Datta +3
We present results from \textit{Chandra} X-ray observations and 325 MHz Giant Metrewave Radio Telescope (GMRT) observations of the massive and X-ray luminous cluster of galaxies Ab…
A low-frequency radio halo survey of the South Pole Telescope SZ-selected clusters with the GMRT
Ramij Raja, Majidul Rahaman, Abhirup Datta +3
The presence of non-thermal electrons and large scale magnetic fields in the intra-cluster medium (ICM) is known through the detection of mega-parsec (Mpc) scale diffuse radio sync…
