About this document
Cosmic Strings and Gravitational Waves by Lopmaz is a document available to read on EtoBox.
This document discusses how cosmic strings can affect the cosmological gravitational wave background. It finds that if the early universe contained both radiation and a subdominant component of cosmic strings, this would result in a constant effective potential in the equation governing gravitational wave propagation. This constant potential leads to a critical comoving wave number that discriminates metric perturbations into oscillating and non-oscillating modes. The evolution of the non-oscillating modes
