Abell 1430: A merging cluster with exceptional diffuse radio emission
M. Hoeft, C. Dumba, A. Drabent +16
Diffuse radio emission has been found in many galaxy clusters, predominantly in massive systems which are in the state of merging. The radio emission can usually be classified as r…
New mysteries and challenges from the Toothbrush relic: wideband observations from 550 MHz to 8 GHz
K. Rajpurohit, M. Hoeft, F. Vazza +10
Radio relics are diffuse extended synchrotron sources that originate from shock fronts induced by galaxy cluster mergers. The actual particle acceleration mechanism at the shock fr…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
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…
