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…
Radio observations of the merging galaxy cluster Abell 520
D. N. Hoang, T. W. Shimwell, R. J. van Weeren +13
We examine the possible acceleration mechanisms of the relativistic particles responsible for the extended radio emission in Abell 520. We used new LOFAR 145 MHz, archival GMRT 323…
Characterizing the radio emission from the binary galaxy cluster merger Abell 2146
D. N. Hoang, T. W. Shimwell, R. J. van Weeren +8
Collisions of galaxy clusters generate shocks and turbulence in the intra-cluster medium (ICM). The presence of relativistic particles and magnetic fields is inferred through the d…
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…
Deep Very Large Array observations of the merging cluster CIZA J2242.8+5301: continuum and spectral imaging
G. Di Gennaro, R. J. van Weeren, M. Hoeft +14
Despite progress in understanding radio relics, there are still open questions regarding the underlying particle acceleration mechanisms. In this paper we present deep 1--4 GHz VLA…
Radio observations of the double-relic galaxy cluster Abell 1240
D. N. Hoang, T. W. Shimwell, R. J. van Weeren +16
We present LOFAR MHz images of the merging galaxy cluster Abell 1240 that hosts double radio relics. In combination with the GMRT MHz and VLA GHz data, we…
