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.
