Evolution of hydromagnetic turbulence from the electroweak phase transition
Axel Brandenburg, Tina Kahniashvili, Sayan Mandal +3
We present new simulations of decaying hydromagnetic turbulence for a relativistic equation of state relevant to the early universe. We compare helical and nonhelical cases either…
Scale-invariant helical magnetic field evolution and the duration of inflation
Tina Kahniashvili, Axel Brandenburg, Ruth Durrer +2
We consider a scale-invariant helical magnetic field generated during inflation. We show that, if the mean magnetic helicity density of such a field is measured, it can be used to…
The evolution of primordial magnetic field since its generation
Tina Kahniashvili, Axel Brandenburg, Alexander G. Tevzadze
We study the evolution of primordial magnetic fields in an expanding cosmic plasma. For this purpose we present a comprehensive theoretical model to consider the evolution of MHD t…
Nonhelical inverse transfer of a decaying turbulent magnetic field
Axel Brandenburg, Tina Kahniashvili, Alexander G. Tevzadze
In the presence of magnetic helicity, inverse transfer from small to large scales is well known in magnetohydrodynamic (MHD) turbulence and has applications in astrophysics, cosmol…
Evolution of Primordial Magnetic Fields from Phase Transitions
Tina Kahniashvili, Alexander G. Tevzadze, Axel Brandenburg +1
We consider the evolution of primordial magnetic fields generated during cosmological, electroweak or QCD, phase transitions. We assume that the magnetic field generation can be de…
Constraining primordial magnetic fields through large scale structure
Tina Kahniashvili, Yurii Maravin, Aravind Natarajan +2
We study primordial magnetic field effects on the matter perturbations in the Universe. We assume magnetic field generation prior to the big bang nucleosynthesis (BBN), i.e. during…
