Can galactic magnetic fields diffuse into the voids?
Oindrila Ghosh, Axel Brandenburg, Chiara Caprini +2
Cosmic voids are magnetized at the level of at least G on Mpc scales, as implied by blazar observations. We show that an electrically conducting plasma is present in the…

Intergalactic magnetism in a gamma-ray beam as a model of Porphyrion
A. Neronov, F. Vazza, A. Brandenburg +1
We estimate the magnetic field in the jets of the recently discovered 7 Mpc long Porphyrion system. We use non-detection of the system in gamma-rays to derive a lower bound on the…
