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…
Deep low-frequency radio observations of Abell 2256 II: The ultra-steep spectrum radio halo
K. Rajpurohit, E. Osinga, M. Brienza +17
We present the first detailed analysis of the radio halo in the merging galaxy cluster Abell 2256 using the LOFAR, uGMRT, and VLA. These observations combined with archival X-ray d…
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…
Particle re-acceleration and diffuse radio sources in the galaxy cluster Abell 1550
T. Pasini, H. W. Edler, M. Brüggen +13
We study diffuse radio emission in the galaxy cluster A1550, with the aim of constraining particle re-acceleration in the intra-cluster medium. We exploit observations at four diff…
GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) I: Survey Description and Initial Data Release
Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne +15
We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 - 231 MHz and Declinations south of have been performed with the Mur…
The Coma cluster at LOFAR frequencies II: the halo, relic, and a new accretion relic
A. Bonafede, G. Brunetti, L. Rudnick +26
We present LOw Frequency ARray observations of the Coma cluster field at 144\,MHz. The cluster hosts one of the most famous radio halos, a relic, and a low surface-brightness bridg…
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 merging galaxy cluster Abell 3266 at low radio frequencies
S. W. Duchesne, M. Johnston-Hollitt, C. J. Riseley +2
We present new low-frequency (-216 MHz) observations of the complex merging galaxy cluster Abell 3266. These new observations are taken with the Murchison Widefield Array (M…
The galaxy group NGC 507: newly detected AGN remnant plasma transported by sloshing
M. Brienza, L. Lovisari, K. Rajpurohit +15
Jets from active galactic nuclei (AGN) are known to recurrently enrich their surrounding medium with mildly-relativistic particles and magnetic fields. Here, we present a detailed…
