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…
LOFAR observations of galaxy clusters in HETDEX
R. J. van Weeren, T. W. Shimwell, A. Botteon +20
Diffuse cluster radio sources, in the form of radio halos and relics, reveal the presence of cosmic rays and magnetic fields in the intracluster medium (ICM). These cosmic rays are…
A perfect power-law spectrum even at highest frequencies: The Toothbrush relic
K. Rajpurohit, F. Vazza, M. Hoeft +12
Radio relics trace shock fronts generated in the intracluster medium (ICM) during cluster mergers. The particle acceleration mechanism at the shock fronts is not yet completely und…
