Cosmic magnetic fields from velocity perturbations in the early Universe
Gerold Betschart, Peter K. S. Dunsby, Mattias Marklund
We show, using a covariant and gauge-invariant charged multifluid perturbation scheme, that velocity perturbations of the matter-dominated dust Friedmann-Lemaitre-Robertson-Walker…
The electromagnetic signature of black hole ringdown
C. Clarkson, M. Marklund, G. Betschart +1
We investigate generation of electromagnetic radiation by gravitational waves interacting with a strong magnetic field in the vicinity of a vibrating Schwarzschild black hole. Such…
Modulational instabilities in neutrino--anti-neutrino interactions
Mattias Marklund, Padma K. Shukla, Gerold Betschart +3
We analyze the collective behavior of neutrinos and antineutrinos in a dense background. Using the Wigner transform technique, it is shown that the interaction can be modelled by a…
