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…
The detection of cluster magnetic fields via radio source depolarisation
E. Osinga, R. J. van Weeren, F. Andrade-Santos +7
It has been well established that galaxy clusters have magnetic fields. The exact properties and origin of these magnetic fields are still uncertain even though these fields play a…
MeerKAT view of the diffuse radio sources in Abell 3667 and their interactions with the thermal plasma
F. de Gasperin, L. Rudnick, A. Finoguenov +11
During their lifetime, galaxy clusters grow through the accretion of matter from the filaments of the large scale structure and from mergers with other clusters. These mergers rele…
Turbulent magnetic fields in the merging galaxy cluster MACS J0717.5+3745: polarization analysis
K. Rajpurohit, M. Hoeft, D. Wittor +20
We present wideband polarimetric observations, obtained with the Karl G. Jansky Very Large Array (VLA), of the merging galaxy cluster MACS J0717.5+3745, which hosts one of the most…
An ALMA+ACA measurement of the shock in the Bullet Cluster
Luca Di Mascolo, Tony Mroczkowski, Eugene Churazov +9
The thermal Sunyaev-Zeldovich (SZ) effect presents a relatively new tool for characterizing galaxy cluster merger shocks, traditionally studied through X-ray observations. Widely r…
Observations of a nearby filament of galaxy clusters with the Sardinia Radio Telescope
V. Vacca, M. Murgia, F. Govoni +29
We report the detection of diffuse radio emission which might be connected to a large-scale filament of the cosmic web covering a 8deg x 8deg area in the sky, likely associated wit…
