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…

A radio continuum view of Stephan's Quintet: age, dynamics and origin of the shock

K. Rajpurohit, E. O'Sullivan, G. Schellenberger +10

We present a detailed, multi-band radio continuum study of the compact galaxy group Stephan's Quintet (HCG 92). We use a combination of new (MeerKAT, uGMRT) and archival (LOFAR, VL…

A "MeerKAT-meets-LOFAR" Study of 2A 0335+096: Discovery of a Complex 500 kpc Radio Halo in a Disturbed Cool-Core Cluster

C. J. Riseley, R. J. van Weeren, L. Lovisari +9

The emerging picture of radio haloes and mini-haloes in galaxy clusters is more blurred and far less distinct than once thought. While both trace cosmic ray electrons and magnetic…

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…

Radio Halos in Galaxy Clusters as unveiled by the SKA telescope

R. Cassano, G. Di Gennaro, V. Cuciti +24

Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…

The Treble Clef radio phoenix and its old nonthermal filaments

A. Botteon, M. Brienza, K. Rajpurohit +15

By inspecting data from the LOFAR Two-meter Sky Survey (LoTSS), we noticed a peculiar bright and filamentary radio source at low-galactic latitude (). This source,…
