Leading-order nonlinear gravitational waves from reheating magnetogeneses
Yutong He, Alberto Roper Pol, Axel Brandenburg
We study the leading-order nonlinear gravitational waves (GWs) produced by an electromagnetic (EM) stress in reheating magnetogenesis scenarios. Both nonhelical and helical magneti…
The scalar, vector, and tensor modes in gravitational wave turbulence simulations
Axel Brandenburg, Grigol Gogoberidze, Tina Kahniashvili +3
We study the gravitational wave (GW) signal sourced by primordial turbulence that is assumed to be present at cosmological phase transitions like the electroweak and quantum chromo…
Circular Polarization of Gravitational Waves from Early-Universe Helical Turbulence
Tina Kahniashvili, Axel Brandenburg, Grigol Gogoberidze +2
We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety…
NANOGrav signal from MHD turbulence at QCD phase transition in the early universe
A. Neronov, A. Roper Pol, C. Caprini +1
The NANOGrav collaboration has recently reported evidence for the existence of a stochastic gravitational wave background in the 1-100 nHz frequency range. We argue that such backg…
E and B polarizations from inhomogeneous and solar surface turbulence
Axel Brandenburg, Andrea Bracco, Tina Kahniashvili +4
Gradient- and curl-type or E- and B-type polarizations have been routinely analyzed to study the physics contributing to the cosmic microwave background polarization and galactic f…
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…
