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…
Generation of nanoflares in the Crab pulsar
G. Machabeli, I. Malov, G. Gogoberidze
We study dynamics of drift waves in the pair plasma of pulsar magnetosphere. It is shown that nonlinear of the drift waves with plasma particles leads to the formation of small sca…
Imbalanced magnetohydrodynamic turbulence modified by velocity shear in the solar wind
Grigol Gogoberidze, Yuriy Voitenko
We study incompressible imbalanced magnetohydrodynamic turbulence in the presence of background velocity shears. Using scaling arguments, we show that the turbulent cascade is sign…
Electrostatic plasma instabilities driven by neutral gas flows in the solar chromosphere
G. Gogoberidze, Y. Voitenko, S. Poedts +1
We investigate electrostatic plasma instabilities of Farley-Buneman (FB) type driven by quasi-stationary neutral gas flows in the solar chromosphere. The role of these instabilitie…
Yaglom law in the expanding solar wind
G. Gogoberidze, S. Perri, V. Carbone
We study the Yaglom law, which relates the mixed third order structure function to the average dissipation rate of turbulence, in a uniformly expanding solar wind by using the two…
