Gravitational waves from cosmic strings with friction: analytical approximations and parameter space
Sergei Mukovnikov, Lara Sousa
We derive analytical approximations to describe the ultra-high-frequency secondary peak of the stochastic gravitational wave background generated by cosmic strings that is sourced…

Ultra-high frequency gravitational waves from cosmic strings with friction
S. Mukovnikov, L. Sousa
We include the effect of the frictional force caused by interactions between cosmic strings and the particles of the background plasma in the computation of the stochastic gravitat…
