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
We present MeerKAT observations of the galaxy cluster Abell 2034, a massive (M_500=5.21 10^14 solar masses) nearby cluster in a merging state. Previous observations at 144 MHz have…
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…
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…
MeerKAT observations of Abell 1775 and Abell 1795: the discovery of a hadronic radio halo?
R. J. van Weeren, E. Osinga, G. Brunetti +13
Giant radio haloes are diffuse synchrotron sources typically found in merging galaxy clusters, while smaller mini-haloes occur in cool-core clusters. Both trace cosmic-ray electron…
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…
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…
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…
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 Absorption Line Survey Data Release 2: Wideband continuum catalogues and a measurement of the cosmic radio dipole
J. D. Wagenveld, H-R. Klöckner, N. Gupta +18
We present the second data release of the MeerKAT Absorption Line Survey (MALS), consisting of wideband continuum catalogues of 391 pointings observed at L~band. The full wideband…
Exploring the Dynamical Nature and Radio Halo Emission of Abell 384: A Combined Radio, X-ray and Optical Study
Swarna Chatterjee, Denisha Pillay, Abhirup Datta +4
Multiwavelength studies of galaxy clusters are crucial for understanding the complex interconnection of the thermal and non-thermal constituents of these massive structures and unc…

We present the first detailed radio study of the galaxy cluster XMMXCS J2215.9-1738 at = 1.46 using MeerKAT -band (1.3 GHz) observations. We combine our radio observation wi…
DEVILS/MIGHTEE/GAMA/DINGO: The Impact of SFR Timescales on the SFR-Radio Luminosity Correlation
Robin H. W. Cook, Luke J. M. Davies, Jonghwan Rhee +20
The tight relationship between infrared luminosity (L) and 1.4 GHz radio continuum luminosity (L) has proven useful for understanding star formatio…
The MeerKAT Massive Distant Clusters Survey: A Radio Halo in a Massive Galaxy Cluster at z = 1.23
S. P. Sikhosana, M. Hilton, G. Bernardi +9
In the current paradigm, high redshift radio halos are expected to be scarce due to inverse Compton energy losses and redshift dimming, which cause them to be intrinsically faint.…
