Physical insights from the spectrum of the radio halo in MACS J0717.5+3745
K. Rajpurohit, G. Brunetti, A. Bonafede +18
We present new LOFAR observations of the massive merging galaxy cluster MACS J0717.5+3745. The cluster hosts the most powerful radio halo known to date. These new observations, in…
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…
The Coma cluster at LOFAR frequencies I: insights into particle acceleration mechanisms in the radio bridge
A. Bonafede, G. Brunetti, F. Vazza +18
Radio synchrotron emission from the bridges of low-density gas connecting galaxy clusters and groups is a challenge for particle acceleration processes. In this work, we analyse th…
Diffuse Radio Emission from Galaxy Clusters in the LOFAR Two-metre Sky Survey Deep Fields
E. Osinga, R. J. van Weeren, J. Boxelaar +15
Low-frequency radio observations are revealing an increasing number of diffuse synchrotron sources from galaxy clusters, dominantly in the form of radio halos or radio relics. The…
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…
A giant radio bridge connecting two clusters in Abell 1758
A. Botteon, R. J. van Weeren, G. Brunetti +14
Collisions between galaxy clusters dissipate enormous amounts of energy in the intra-cluster medium (ICM) through turbulence and shocks. In the process, Mpc-scale diffuse synchrotr…
