MeerKAT Reveals Evidence of a Radio Megahalo at GHz Frequency
Swarna Chatterjee, Kenda Knowles
Radio megahalos are recently discovered large-scale diffuse synchrotron sources identified through LOFAR observations. We present MeerKAT L-band observations of the massive galaxy…
The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
The paper presents MeerKAT multi‑frequency and polarimetric observations of the merging galaxy cluster Abell 2034, confirming a radio halo, identifying a relic and steep‑spectrum f…
Probing Merger Shocks in Galaxy Clusters in the SKA Era
Arpan Pal, Ruta Kale, Gabriella Di Gennaro +8
Galaxy cluster mergers represent the most energetic phenomena in the Universe since the Big Bang releasing gravitational potential energy of erg, injecting turbul…
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…
A targeted machine learning approach for detecting diffuse radio emission with Astronomaly: Protege
Verlon Etsebeth, Michelle Lochner, Konstantinos Kolokythas +2
Diffuse radio emission in galaxy clusters, such as radio halos, relics, and mini halos, is a key tracer of non-thermal processes, turbulence, and magnetic fields within the intra-c…
The Atacama Cosmology Telescope: DR6 Sunyaev-Zel'dovich Selected Galaxy Clusters Catalog
HSC Collaboration, M. Aguena, S. Aiola +98
We present the results of a search for galaxy clusters in the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) microwave sky maps covering 16293 square degrees in three frequ…
