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…

A LOFAR study of non-merging massive galaxy clusters

Federica Savini, Annalisa Bonafede, Marcus Brueggen +15

Centrally located diffuse radio emission has been observed in both merging and non-merging galaxy clusters. Depending on their morphology and size, we distinguish between giant rad…

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…

Evolutionary phases of merging clusters as seen by LOFAR

Amanda Wilber, Marcus Brüggen, Annalisa Bonafede +13

Massive, merging galaxy clusters often host giant, diffuse radio sources that arise from shocks and turbulence; hence, radio observations can be useful for determining the merger s…
