The spectacular cluster chain Abell 781 as observed with LOFAR, GMRT, and XMM-Newton
A. Botteon, T. W. Shimwell, A. Bonafede +20
A number of merging galaxy clusters show the presence of large-scale radio emission associated with the intra-cluster medium (ICM). These synchrotron sources are generally classifi…
First evidence of diffuse ultra-steep-spectrum radio emission surrounding the cool core of a cluster
Federica Savini, Annalisa Bonafede, Marcus Brueggen +14
Diffuse synchrotron radio emission from cosmic-ray electrons is observed at the center of a number of galaxy clusters. These sources can be classified either as giant radio halos,…
LOFAR discovery of radio emission in MACSJ0717.53745
A. Bonafede, M. Brüggen, D. Rafferty +16
We present results from LOFAR and GMRT observations of the galaxy cluster MACSJ0717.53745. The cluster is undergoing a violent merger involving at least four sub-clusters, a…
LOFAR discovery of a double radio halo system in Abell 1758 and radio/X-ray study of the cluster pair
A. Botteon, T. W. Shimwell, A. Bonafede +14
Radio halos and radio relics are diffuse synchrotron sources that extend over Mpc-scales and are found in a number of merger galaxy clusters. They are believed to form as a consequ…
Discovery of large-scale diffuse radio emission in low-mass galaxy cluster Abell 1931
M. Brüggen, D. Rafferty, A. Bonafede +12
Extended, steep-spectrum radio synchrotron sources are pre-dominantly found in massive galaxy clusters as opposed to groups. LOFAR Two-Metre Sky Survey images have revealed a diffu…
Search for low-frequency diffuse radio emission around a shock in the massive galaxy cluster MACS J0744.9+3927
Amanda Wilber, Marcus Brüggen, Annalisa Bonafede +11
Merging galaxy clusters produce low Mach number shocks in the intracluster medium. These shocks can accelerate electrons to relativistic energies that are detectable at radio frequ…
Studying the late evolution of a radio-loud AGN in a galaxy group with LOFAR
Federica Savini, Annalisa Bonafede, Marcus Brüggen +17
Feedback by radio-loud active galactic nuclei (AGN) in galaxy groups is not fully understood. Open questions include the duty cycle of the AGN, the spatial extent of the radio lobe…
LOFAR discovery of an ultra-steep radio halo and giant head-tail radio galaxy in Abell 1132
A. Wilber, M. Brüggen, A. Bonafede +16
LOFAR observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of 650 kp…
