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…
Revealing the intricacies of radio galaxies and filaments in the merging galaxy cluster Abell 2255. II. Properties of filaments using multi-frequency radio data
E. De Rubeis, M. Bondi, A. Botteon +11
In this paper, we aim to further analyze the filaments in Abell 2255 combining LOFAR data with uGMRT (1260 MHz) and VLA (1520 MHz) data to constrain the spectral shape of the filam…
Resurging from the ashes: A spectral study of seven candidate revived radio fossils in nearby low-mass galaxy clusters
L. Bruno, A. Botteon, D. Dallacasa +17
Complex energy transfer processes in the intracluster medium (ICM) can revive fossil (with spectral ages Myr) plasma initially generated by radio galaxies. This leads to t…
Revealing the intricacies of radio galaxies and filaments in the merging galaxy cluster Abell 2255. I. Insights from deep LOFAR-VLBI sub-arcsecond resolution images
E. De Rubeis, M. Bondi, A. Botteon +7
High sensitivity of modern interferometers is revealing a plethora of filaments surrounding radio galaxies, especially in galaxy cluster environments. The morphology and spectral c…
