Polarisation and Faraday rotation measure imaging at metre wavelengths with sub-arcsecond resolution: a foundational calibration strategy
R. J. van Weeren, J. M. G. H. J. de Jong, X. K Le Saux +12
Low-frequency radio polarimetric observations provide a powerful probe of magnetic fields in astrophysical sources and the intervening medium, as well as magnetospheric emission fr…
The ultra low-frequency spectral properties of bright extended radio galaxies in the 3CRR catalogue
J. M. Boxelaar, F. De Gasperin, M. J. Hardcastle +2
Context. Active galactic nuclei (AGN) jets are fundamental drivers of galaxy evolution, injecting kinetic energy into their environments. The large-scale morphology and spectral pr…
A high-resolution study of the double radio relic system in MACS J1752.0+4440
M. Della Chiesa, A. Botteon, A. Bonafede +6
Radio relics are diffuse, extended synchrotron sources located at the outskirts of merging galaxy clusters. Their origin has been linked with shock waves injected into the intraclu…
Investigating the radio emission in the Perseus cluster with LOFAR sub-80 MHz LBA
C. Groeneveld, R. J. van Weeren, M. -L. Gendron-Marsolais +7
The Perseus cluster is a nearby cool-core galaxy cluster that hosts an archetypal radio mini-halo. Recent Low Frequency Array (LOFAR) High Band Antenna (HBA) observations at 120 -…
Molecular Clouds Resolved at the Onset of Cosmic Noon
Bjorn Emonts, Matthew Lehnert, Mingyu Li +10
We present the discovery of seven molecular clouds in the radio galaxy B2 0902+34 at redshift z=3.4. These clouds are detected as CO(0-1) absorption features against the bright rad…
Early Results from the Coma Legacy IFU Survey (CLIFS): Ram Pressure Induced Shocks and Ionization in Jellyfish Tails
Lauren M. Foster, Ian D. Roberts, Laura C. Parker +6
Jellyfish galaxies, which exhibit tails of gas opposite to their direction of motion, are a galaxy population showcasing the most extreme effects of ram pressure stripping (RPS). W…
