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.
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" 😅
#COSMOMAG-related Post-Docs in CERN, and Laboratoire de Physique de l’École Normale Supérieure with C. Caprini, with projects related to
- The generation, evolution, and properties of primordial magnetic fields at the electroweak energy scale
- The generation, evolution, and properties of primordial magnetic fields at the QCD energy scale
please share with potentially interested applicants.
DEADLINE 20 January!

"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).
Big day! Carrying the official announcements of funded #ERC #SynergyGrants, including the one I am part of:
which will study the first micro-seconds (!) of the Universe using magnetic fields (and gravitational waves).
Interesting 6 years ahead!!
