The MeerKAT Massive Distant Clusters Survey: detection of diffuse radio emission in galaxy clusters at

Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +11

Diffuse, low surface-brightness radio emission in merging galaxy clusters provides insights into cosmic structure formation, the growth of magnetic fields, and turbulence. This pap…

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…

Radial Profiles of Radio Halos in Massive Galaxy Clusters: Diffuse Giants Over 2 Mpc

K. Rajpurohit, A. Botteon, E. O'Sullivan +9

We present new, high frequency radio observations of the merging galaxy clusters PLCK G287.0+32.9, Abell 2744, and Bullet. These clusters are known to host Mpc scale sources,…

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…
