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…
A deep study of A399-401: An application for wide-field facet calibration
J. M. G. H. J. de Jong, R. J. van Weeren, A. Botteon +6
We examine the particle acceleration mechanism in the Mpc-scale bridge between Abell 399 and Abell 401 and assess in particular if the synchrotron emission originates from first-or…
Galaxy clusters enveloped by vast volumes of relativistic electrons
V. Cuciti, F. de Gasperin, M. Brueggen +12
The central regions of galaxy clusters are permeated by magnetic fields and filled with relativistic electrons. When clusters merge, the magnetic fields are amplified and relativis…
Radio fossils, relics, and haloes in Abell 3266: cluster archaeology with ASKAP-EMU and the ATCA
C. J. Riseley, E. Bonnassieux, T. Vernstrom +21
Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant substructure. We present new, highly sensitive radio continuum observations of Abell 3266 perfo…
Possible discovery of Calvera's supernova remnant
M. Arias, A. Botteon, C. G. Bassa +13
We report the discovery of a ring of low surface brightness radio emission around the Calvera pulsar, a high Galactic latitude, isolated neutron star, in the LOFAR Two-metre Sky Su…
Nearby galaxies in LoTSS-DR2: insights into the non-linearity of the radio-SFR relation
V. Heesen, M. Staffehl, A. Basu +24
Context. Cosmic rays and magnetic fields are key ingredients in galaxy evolution, regulating both stellar feedback and star formation. Their properties can be studied with low-freq…
