Left panel: Examples of GW spectra from cosmic strings with differing tensions Gμ. The dashed lines show the impact of the variation in the number of SM degrees of freedom. Right panel: Detail of the effect on the GW spectrum for the case \(G \mu = 10^{-11}\) of a new particle threshold at various energies \(T_{\Delta }\ge 100\text{ MeV}\) with an increase \(\Delta g_{*} = 100\) in the number of relativistic degrees of freedom
