Isochrones in primordial magnetic field evolution
Axel Brandenburg, Mattia Cielo, Oksana Iarygina +1
In the early universe, a primordial magnetic field undergoes a turbulent decay while its length scale increases due to an inverse cascade. The size of the largest processed eddy sc…
Magnetic field spreading from stellar and galactic dynamos into the exterior
Axel Brandenburg, Oindrila Ghosh, Franco Vazza +1
The exteriors of stellar and galactic dynamos are usually modeled as current-free potential fields. A more realistic description might instead be that of a force-free magnetic fiel…
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…
Vorticity production and survival in viscous and magnetized cosmologies
F. Dosopoulou, F. Del Sordo, C. G. Tsagas +1
We study the role of viscosity and the effects of a magnetic field on a rotating, self-gravitating fluid, using Newtonian theory and adopting the ideal magnetohydrodynamic approxim…
