Deep VLA observations of the cluster 1RXS J0603.3+4214 in the frequency range 1-2 GHz
K. Rajpurohit, M. Hoeft, R. J. van Weeren +11
We report L-band VLA observations of 1RXS J0603.3+4214, a cluster that hosts a bright radio relic, known as the Toothbrush, and an elongated giant radio halo. These new observation…
Merging Cluster Collaboration: Optical and Spectroscopic Survey of a Radio-Selected Sample of Twenty Nine Merging Galaxy Clusters
Nathan Golovich, William A. Dawson, David M. Wittman +11
Multi-band photometric and multi-object spectroscopic surveys of merging galaxy clusters allow for the characterization of the distributions of constituent dark matter and galaxy p…
Gentle re-energisation of electrons in merging galaxy clusters
F. de Gasperin, H. T. Intema, T. W. Shimwell +6
Galaxy clusters are the most massive constituents of the large-scale structure of the Universe. While the hot thermal gas that pervades galaxy clusters is relatively well understoo…
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…
VLA Radio Observations of the HST Frontier Fields Cluster Abell 2744: The Discovery of New Radio Relics
C. J. J. Pearce, R. J. van Weeren, F. Andrade-Santos +12
Cluster mergers leave distinct signatures in the ICM in the form of shocks and diffuse cluster radio sources that provide evidence for the acceleration of relativistic particles. H…
Mystery solved: discovery of extended radio emission in the merging galaxy cluster Abell 2146
J. Hlavacek-Larrondo, M. -L. Gendron-Marsolais, D. Fecteau-Beaucage +11
Abell 2146 () is a massive galaxy cluster currently undergoing a spectacular merger in the plane of the sky with a bullet-like morphology. It was the first system in which…
