Science with the space-based interferometer eLISA. II: gravitational waves from cosmological phase transitions

“…• Magnetohydrodynamic (MHD) turbulence in the plasma forming after the bubbles have collided [21][22][23][24][25][26].…”

Detection of gravitational waves from the QCD phase transition with pulsar timing arrays

“…Detailed semi-analytical and numerical calculations have been performed in the past in order to calculate the GW energy spectrum from first order phase transitions [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. In this paper we simply use analytic fits to the most recent results, as presented in the following.…”

“…One example of such violent processes are first order phase transitions [17,[21][22][23][24], which can lead to GW production via the collision of bubbles of the true vacuum [25][26][27][28][29][30][31][32][33] and via the turbulence and magnetic fields they can induce in the cosmic plasma [34][35][36][37][38][39][40][41].…”

Gravitational waves from hidden QCD phase transition

“…where h is the dimensionless Hubble parameter, Ω ϕ stands for the scalar field contribution from collisions of bubble walls [61][62][63][64][65][66], Ω sw for the contribution from sound waves in plasma after the bubble collisions [67][68][69][70], and Ω turb for the contribution from magnetohydrodynamic (MHD) turbulence in plasma [71][72][73][74]. Following [12], each contribution is given for a given set of the parameters (T t , α,β) with the velocity of bubble wall v w and the κ ϕ , κ v , and κ turb which are the fraction of vacuum energy, respectively, converted into gradient energy of scalar field, bulk motion of the fluid, and MHD turbulence.…”
