The spectrum of the persistent radio source associated with FRB 20190417A
L. Bruno, D. Pelliciari, G. Bernardi +3
Persistent radio sources (PRSs) are (sub-)parsec-scale compact non-thermal continuum sources associated with some repeating fast radio bursts (FRBs). Their nature is debated, but t…

Cosmological simulations of the generation of cluster-scale radio emission from turbulent re-acceleration
Luca Beduzzi, Franco Vazza, Virginia Cuciti +3
Context. The recent discovery of so-called mega radio halos as a new class of diffuse, steep-spectrum radio sources in clusters of galaxies has raised questions about the origin an…
