Numerical analysis of magnetogenesis' primordial mechanism

Abstract

We present the results of Relativistic Magnetohydrodynamic simulations utilizing initial conditions from both the Electroweak and quantum chromodynamics phase transitions to see if seed magnetic fields may be generated via the Biermann battery mechanism of magnetogensis. These simulations occur in a simulated early universe between 10 −11 s and 10 -3 s after the Big Bang. We find that magnetic fields on the order of 10 −19 G are generated on small scales and magnetic fields of 10 −25 G are generated on the Mpc scale. Further work is needed to understand how these fields may have impacted the large-scale structures we observe today. KEYWORDSBiermann battery -magnetogenesis -phase transition -relativistic plasma 1
