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…
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…
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…
