ASKAP reveals giant radio halos in two merging SPT galaxy clusters -- Making the case for a direction-dependent pipeline --
Amanda G. Wilber, Melanie Johnston-Hollitt, Stefan W. Duchesne +4
Early science observations from the Australian Square Kilometre Array Pathfinder (ASKAP) have revealed clear signals of diffuse radio emission associated with two clusters detected…
Warped diffusive radio halo around the quiescent spiral edge-on galaxy NGC 4565
V. Heesen, L. Whitler, P. Schmidt +12
Cosmic rays play a pivotal role in launching galactic winds, particularly in quiescently star-forming galaxies where the hot gas alone is not sufficient to drive a wind. Except for…
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…
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…
First evidence of diffuse ultra-steep-spectrum radio emission surrounding the cool core of a cluster
Federica Savini, Annalisa Bonafede, Marcus Brueggen +14
Diffuse synchrotron radio emission from cosmic-ray electrons is observed at the center of a number of galaxy clusters. These sources can be classified either as giant radio halos,…
LOFAR discovery of radio emission in MACSJ0717.53745
A. Bonafede, M. Brüggen, D. Rafferty +16
We present results from LOFAR and GMRT observations of the galaxy cluster MACSJ0717.53745. The cluster is undergoing a violent merger involving at least four sub-clusters, a…
