Monitoring the power spectrum of magnetic field fluctuations across the simulated intracluster medium
T. Bartalesi, F. Vazza, S. Ettori +2
Thanks to the current and forthcoming radio interferometers, Faraday rotation measure maps extend out to the outskirts of galaxy clusters. Interpreted through models of the magneti…
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…
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,…
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…
Estimating Flux Densities of Diffuse Cosmological Radio Sources Exploiting Vision Transformers
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +3
We present TUNA, a Vision-Transformer based network adapted from segmentation to flux regression for faint, diffuse radio emission. Trained on LOFAR-like mock observations derived…
Mapping Diffuse Radio Sources Using TUNA: A Transformer-Based Deep Learning Approach
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +6
Vision Transformers are used via a customized TransUNet architecture, which is a hybrid model combining Transformers into a U-Net backbone, to achieve precise, automated, and fast…
