Imprints of primordial magnetic fields in gravitational collapse during early structure formation
Jennifer Schober, Molly Abramson, Sayan Mandal +2
Context. Primordial magnetic fields (PMFs) generated in the early Universe might have left observable imprints on present-day large-scale structure. However, the spatial scales on…
The universal growth of magnetic energy during the nonlinear phase of subsonic and supersonic small-scale dynamos
Neco Kriel, James R. Beattie, Mark R. Krumholz +2
Small-scale dynamos (SSDs) amplify magnetic fields in turbulent plasmas. Theory predicts nonlinear magnetic energy growth , but this scali…
Are magnetic fields in cosmic voids primordial?
Deepen Garg, Ruth Durrer, Jennifer Schober
The nature of magnetic fields in the voids of the large-scale structure of the Universe has been a multifaceted open puzzle for decades. On one hand, their origin is not clear with…
Forward cascade of large-scale primordial magnetic fields during structure formation
Molly Abramson, Emma Clarke, Tina Kahniashvili +3
The origin of large scale magnetic fields in the Universe is widely thought to be from early Universe processes, like inflation or phase transitions. These magnetic fields evolve v…
