I study the cosmic web, extragalactic magnetism and clusters of galaxies with colorful simulations.
Less #AI and more tiramisu in our lives!

This model considered that some radio jets, instead of fast moving plasmas ejected by AGN, can be the result of high energy beams of gamma-rays which convert into electron-positron pairs, and then emit via synchrotron if they encounter a high enough (>10nG) magnetic field in filaments.
I spoke of this scenario here: https://mastodon.social/@franco_vazza/113429246617344393
We actually thought of killing this model with cosmological simulations..but we could not and the models survives. More in a future publication
Kudos to Valerio Tritapepe, who has successfully defended his Master Thesis in #astrophysics last Friday at the University of #Bologna
Valerio has for the first time attempted a statistical validation or rejection of an unorhtodox model (by Neronov, myself et al. https://arxiv.org/abs/2411.01640) to explain the existence of the longest and straightest radio jets in the Universe, based on realistic simulations of the magnetic cosmic web.
He got the highest grade (110+Laude) š¾
Please enjoy this stunning collection of portraits of #solar surface turmoils, #flares and else, all produced by Carlo Casoli's from the University of #Bologna with his own telescope and filters:

really really impressive details of magnetic-field driven structures across many scales!
I like this infographic showing different modalities of propagation for charged and neutral cosmic rays in the cosmic web, in this new article on #astroph
"The āForgottenā Neutrons: Implications for the Propagation
of High-Energy Cosmic Rays in Magnetized Astrophysical
and Cosmological Structures" by E. Owen et al. https://arxiv.org/pdf/2603.25060
