Conclusion of a 2-weeks PhD school organised at Nordita (Stockholm) within our newborn #COSMOMAG project. I hope it was a nice closing for the ~30 students who visited us, and who hopefully by now have a more in-depth understanding of the phenomenology of cosmic #magnetism and of its incredible potential to unlock some of the biggest mysteries in the Universe.

One piece of yesterday lectures at Nordita from our #COSMOMAG school: how a discovery during the late stage of M. #Faraday's career turned a failure in optical astronomy into a vertiginous progress for radio astronomy.

"Faraday Rotation" is the most powerful we have to perform magnetic tomography of the Universe and study the 3 dimensional distribution of B in clusters and possibly filaments of galaxies

Todays and yesterday lectures at Nordita for our #COSMOMAG school:
connecting linear and non-linear stages of cosmic structure formation to potential impact of primordial magnetic fields on halo formation and their clustering.

I begun yesterday a full one week every -day teaching at the Winter Astrophysics School at Nordita (Stockholm) about primordial magnetic fields and their evolution, pretty much connected with our incoming #COSMOMAG project. Usually when you prepare lectures, you learn a lot.
My goal is to show the connections between cosmic structure formation and magnetism.
Will the students learn more, or I?

Kickoff of the Nordita Winter School on Cosmological Magnetic Fields we organised within #COSMOMAG in Stockholm, with about 40 international participants (mostly PhD students), which will last 2 intense weeks.

Remarkable quote from lecture one by A. Neronov: "There's nothing wrong with the Universe having magnetic fields" 😅

"Magnetic field spreading from stellar and galactic dynamos into the exterior" by A. Brandenburg, O. Ghosh, myself and A. Neronov

https://arxiv.org/pdf/2512.17770

It is the direct numerical simulation, using the PENCIL code, of how magnetic fields produced by the mean-field dynamo in (very idealised) galaxies distribute over large distances (i.e. potentially into voids).
