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…
