Full analytical approximation to the stochastic gravitational wave background generated by cosmic string networks
Lara Sousa, Pedro P. Avelino, Guilherme S. F. Guedes
We derive a full analytical approximation to the stochastic gravitational wave background generated by the loops that are produced throughout the cosmological evolution of cosmic s…

Signature of inflation in the stochastic gravitational wave background generated by cosmic string networks
G. S. F. Guedes, P. P. Avelino, L. Sousa
A cosmic string network created during an inflationary stage in the early Universe - here defined as i-string network - is expected to enter a transient stretching regime during in…
