Nonthermal phenomena in the center of Abell 1775: An 800 kpc head-tail, revived fossil plasma and slingshot radio halo
A. Botteon, S. Giacintucci, F. Gastaldello +15
Thermal gas in the center of galaxy clusters can show substantial motions that generate surface-brightness and temperature discontinuities known as cold fronts. The motions may be…
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…
Revived Fossil Plasma Sources in Galaxy Clusters
S. Mandal, H. T. Intema, R. J. van Weeren +10
It is well established that particle acceleration by shocks and turbulence in the intra-cluster medium can produce cluster-scale synchrotron emitting sources. However, the detailed…
Ultra-steep spectrum emission in the merging galaxy cluster Abell 1914
S. Mandal, H. T. Intema, T. W. Shimwell +14
A number of radio observations have revealed the presence of large synchrotron-emitting sources associated with the intra-cluster medium. There is strong observational evidence tha…
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…
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…
