The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
The Planck clusters in the LOFAR sky. I. LoTSS-DR2: new detections and sample overview
A. Botteon, T. W. Shimwell, R. Cassano +23
Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM) and manifest themselves as diffuse sources of synchrotron emission observable at radio wavelength…
On the Polarisation of Radio Relics
Matthias Hoeft, Kamlesh Rajpurohit, Denis Wittor +2
Radio relics are extended radio emission features which trace shock waves in the periphery of galaxy clusters originating from cluster mergers. Some radio relics show a highly pola…
A LOFAR-uGMRT spectral index study of distant radio halos
G. Di Gennaro, R. J. van Weeren, R. Cassano +9
Context. Radio halos are megaparsec-scale diffuse radio sources{ mostly} located at the centres of merging galaxy clusters. The common mechanism invoked to explain their origin is…
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…
The great Kite in the sky: a LOFAR observation of the radio source in Abell 2626
A. Ignesti, T. Shimwell, G. Brunetti +15
The radio source at the center of the galaxy cluster Abell 2626, also known as the Kite, stands out for its unique morphology composed of four, symmetric arcs. Previous studies hav…
