Odd radio circle J1555+2726: Observational evidence for shock re-acceleration of fossil plasma
L. Bruno, B. Koribalski, R. P. Norris +7
Context. Odd radio circles (ORCs) are peculiar extragalactic sources recently discovered. They are characterised by one or more bright rings extending on scales of hundreds of kilo…
Cosmic Evolution Survey: LOFAR 144 MHz imaging of the COSMOS field
E. Vardoulaki, T. Shimwell, M. J. Hardcastle +18
We present the first deep, targeted LOFAR 144 MHz source catalogue of the COSMOS field, together with the first 144 MHz source counts in this field. The data comprise 48 h of obser…
The LOFAR Decametre Sky Survey (LoDeSS) I. Survey description and first data release
C. M. Cordun, C. Groeneveld, H. W. Edler +12
The decametre radio sky (- MHz) remains largely unexplored due to strong ionospheric distortions and severe radio-frequency interference. Despite its scientific potent…
The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
We present MeerKAT observations of the galaxy cluster Abell 2034, a massive (M_500=5.21 10^14 solar masses) nearby cluster in a merging state. Previous observations at 144 MHz have…
The topology of the magnetic field in Abell 2255 out to its virial radius. Results from the LOFAR Galaxy Cluster Ultra-Deep Field
A. Botteon, R. J. van Weeren, Y. Hu +14
We present the LOFAR Galaxy Cluster Ultra-Deep Field, in which 336 h of LOFAR observations at 120168 MHz have been collected on the nearby () cluster Abell 2255. This m…
Galaxy clusters in the LoTSS-DR3: Catalogues and detection pipeline for diffuse radio emission
C. Stuardi, G. Di Gennaro, A. Botteon +19
The third data release of the LOFAR Two-metre Sky Survey provides an unprecedented view of the northern sky at 144 MHz. While compact sources can be efficiently identified with aut…
Mapping the emission and spectral properties of the FRI radio galaxy 3C 449 with LOFAR and the VLA
Luca Ricci, Luisa Ostorero, Raffaella Morganti +3
The jets and lobes of nearby radio galaxies are ideal laboratories to explore the spectral and dynamical evolution of the radio-emitting plasma that emanates from active galactic n…
The LOFAR sub-arcsecond view of the high-redshift radio relic in PSZ2G091.83+26.11
G. Di Gennaro, R. Timmerman, M. Hoeft +14
Enhanced inverse Compton (IC) losses at high redshift steepen diffuse radio spectra in galaxy clusters, making low-frequency (~100 MHz) observations favorable. However, low-frequen…
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)…
