Metastable cosmic strings produce a gravitational wave background that is best modeled with three parameters (string tension Gμ plus independent time scales t_LB and t_NC), yielding a compact analytical spectrum when t_LB greatly exceeds t_NC.

Giant vortex strings in 3+1D Abelian Higgs models admit essentially exact solutions that fall into sharply distinct phases in the large-n limit, determined by the form of the Higgs potential and governing their binding energies and stability.
Numerical perturbation analysis shows non-topological Z' strings in the minimal 331 model remain stable only near the semilocal limit θ_S ≈ π/2 even after tuning Higgs self-couplings.
