The LOFAR Two-metre Sky Survey: VII. Third Data Release

T. W. Shimwell, M. J. Hardcastle, C. Tasse +99

We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…

A MeerKAT-meets-LOFAR study of Abell 1413: a moderately disturbed non-cool-core cluster hosting a kpc 'mini'-halo

C. J. Riseley, N. Biava, G. Lusetti +12

Many relaxed cool-core clusters host diffuse radio emission on scales of hundreds of kiloparsecs: mini-haloes. However, the mechanism responsible for generating them, as well as th…

VLBI Imaging of high-redshift galaxies and protoclusters at low radio frequencies with the International LOFAR Telescope

C. M. Cordun, R. Timmerman, G. K. Miley +4

It has long been known that luminous, ultra-steep spectrum radio sources are preferentially associated with massive galaxies at high redshifts. Here we describe a pilot project dir…

V-LoTSS: The Circularly-Polarised LOFAR Two-metre Sky Survey

J. R. Callingham, T. W. Shimwell, H. K. Vedantham +44

We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date. We use the second data release of the 144 MHz LOFAR Two-metr…

Origin of the ring structures in Hercules A -- Sub-arcsecond 144 MHz to 7 GHz observations

R. Timmerman, R. J. van Weeren, J. R. Callingham +18

The prominent radio source Hercules A features complex structures in its radio lobes. Although it is one of the most comprehensively studied sources in the radio sky, the origin of…
