Extended radio emission in and around the merging cluster A520 as seen by MeerKAT
S. Giacintucci, W. D. Cotton, M. Markevitch +3
We present results from a deep MeerKAT 1.28 GHz observation of Abell 520, a galaxy cluster in the middle of a merger and a treasure trove of merger-generated phenomena. MeerKAT's c…
Multiphase gas offsets in the atmospheres of central galaxies and their consequences for SMBH activation I. The hot and warm ionized gas phases
Francesco Ubertosi, Fabrizio Brighenti, Ewan O'Sullivan +10
We investigate the spatial relationships between multi-phase gas components and supermassive black hole (SMBH) activity in a sample of 25 cool core galaxy groups and clusters. Usin…
The MeerKAT Galaxy Cluster Legacy Survey -- II. Catalogue of the diffuse radio emission in MeerKAT-GCLS clusters
Konstantinos Kolokythas, Tiziana Venturi, Kenda Knowles +7
We present a follow-up study focused on cluster-scale diffuse radio emissions in 115 galaxy clusters in the Southern sky, using full-resolution (7.8") and tapered low-resolution (1…
Probing the high frequency variability of NGC 5044: the key to AGN feedback
Gerrit Schellenberger, Ewan O'Sullivan, Laurence David +10
The active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to s…
The radio halo in PLCKESZ G171.94 40.65: Beacon of merging activity
Ramananda Santra, Ruta Kale, Simona Giacintucci +6
We present the first multi-frequency analysis of the candidate ultra-steep spectrum radio halo in the galaxy cluster PLCKESZ G171.9440.65, using the upgraded Giant Metrewave Rad…
ASKAP reveals the radio tail structure of the Corkscrew Galaxy shaped by its passage through the Abell 3627 cluster
Bärbel S. Koribalski, Stefan W. Duchesne, Emil Lenc +12
Among the bent tail radio galaxies common in galaxy clusters are some with long, collimated tails (so-called head-tail galaxies) shaped by their interactions with the intracluster…
