István Pusztai at the Department of Physics at Chalmers is the first author of the paper, recently published in Physical Review Letters. Together with PhD student Andréas Sundström and colleagues in Stockholm and in the US, he has shed new light on the evolution of magnetic fields in the early universe.
The researchers have studied the top candidate mechanism to generate magnetic fields permeating the universe – the dynamo – applying a more accurate description of ionized matter than ever in this context.
"Our new results suggest that the dynamo might have been less effective before the universe became significantly magnetized. This, in turn, can impact how galaxies are formed and galaxy clusters evolved.” says Senior Research Scientist István Pusztai.
