Modified propagation of gravitational waves from the early radiation era
Yutong He, Alberto Roper Pol, Axel Brandenburg
We study the propagation of cosmological gravitational wave (GW) backgrounds from the early radiation era until the present day in modified theories of gravity. Comparing to genera…
Polarization of gravitational waves from helical MHD turbulent sources
Alberto Roper Pol, Sayan Mandal, Axel Brandenburg +1
We use direct numerical simulations of decaying primordial hydromagnetic turbulence with helicity to compute the resulting gravitational wave (GW) production and its degree of circ…
Numerical Simulations of Gravitational Waves from Early-Universe Turbulence
Alberto Roper Pol, Sayan Mandal, Axel Brandenburg +2
We perform direct numerical simulations of magnetohydrodynamic turbulence in the early universe and numerically compute the resulting stochastic background of gravitational waves a…
The timestep constraint in solving the gravitational wave equations sourced by hydromagnetic turbulence
A. Roper Pol, A. Brandenburg, T. Kahniashvili +2
Hydromagnetic turbulence produced during phase transitions in the early universe can be a powerful source of stochastic gravitational waves (GWs). GWs can be modelled by the linear…
