The MIni-Halos in MIni-Clusters (MIMIC) project: New insights into the origin of mini-halos from a LOFAR, uGMRT, and MeerKAT study of diffuse radio emission in Abell 496 and ZwCl 235
F. Ubertosi, S. Giacintucci, A. Botteon +18
We aim at investigating the presence of diffuse radio emission in low-mass (M M), relaxed galaxy clusters. We present a pilot study for the MIMI…
Abell 746: A highly disturbed cluster undergoing multiple mergers
K. Rajpurohit, L. Lovisari, A. Botteon +21
We present deep XMM-Newton, Karl Jansky Very Large Array, and upgraded Giant Metrewave Radio Telescope observations of Abell 746, a cluster that hosts a plethora of diffuse emissio…
Inflationary and phase-transitional primordial magnetic fields in galaxy clusters
Salome Mtchedlidze, Paola Domínguez-Fernández, Xiaolong Du +4
Primordial magnetic fields (PMFs) are possible candidates for explaining the observed magnetic fields in galaxy clusters. Two competing scenarios of primordial magnetogenesis have…
Magnetogenesis and the Cosmic Web: a joint challenge for radio observations and numerical simulations
Franco Vazza, Nicola Locatelli, Kamlesh Rajpurohit +16
The detection of the radio signal from filaments in the cosmic web is crucial to distinguish possible magnetogenesis scenarios. We review the status of the different attempts to de…
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…
Deep low-frequency radio observations of Abell 2256 I: The filamentary radio relic
K. Rajpurohit, R. J. van Weeren, M. Hoeft +22
We present deep and high fidelity images of the merging galaxy cluster Abell 2256 at low frequencies, using the upgraded Giant Metrewave Radio Telescope (uGMRT) and LOw-Frequency A…
Evolution of primordial magnetic fields during large-scale structure formation
Salome Mtchedlidze, Paola Domínguez-Fernández, Xiaolong Du +5
Primordial magnetic fields could explain the large-scale magnetic fields present in the Universe. Inflation and phase transitions in the early Universe could give rise to such fiel…
Morphology of radio relics II: Properties of polarised emission
P. Domínguez-Fernández, M. Brüggen, F. Vazza +7
Radio relics are diffuse radio sources in galaxy clusters that are associated with merger shock waves. Detailed observations of radio relics in total intensity and in polarisation…
The intra-cluster magnetic field in the double relic galaxy cluster Abell 2345
C. Stuardi, A. Bonafede, L. Lovisari +5
Magnetic fields are ubiquitous in galaxy clusters, yet their radial profile, power spectrum, and connection to host cluster properties are poorly known. Merging galaxy clusters hos…
Understanding the radio relic emission in the galaxy cluster MACS J0717.5+3745: spectral analysis
K. Rajpurohit, D. Wittor, R. J. van Weeren +21
Radio relics are diffuse, extended synchrotron sources that originate from shock fronts generated during cluster mergers. The massive merging galaxy cluster MACS J0717.5+3745 hosts…
Fast magnetic field amplification in distant galaxyclusters
Gabriella Di Gennaro, Reinout J. van Weeren, Gianfranco Brunetti +16
In the present-day Universe, magnetic fields pervade galaxy clusters, with strengths of a few microGauss obtained from Faraday Rotation. Evidence for cluster magnetic fields is als…
Morphology of radio relics I: What causes the substructure of synchrotron emission?
P. Domínguez-Fernández, M. Brüggen, F. Vazza +5
High-resolution radio observations of cluster radio relics often show complex spatial and spectral features. However, it is not clear what these features reveal about the underlyin…
