Topological Defects
Domain wall (DW) networks are interesting probes of new physics. They arise from the spontaneous breaking of any discrete symmetry and they have a strong impact on cosmology, producing loud gravitational wave (GW) signals and even primordial black holes. An important example of new physics leading to a long DW epoch is given by a class of well-motivated axion models. I will discuss their GW phenom

We study the gravitational radiation emission efficiency Γ of superconducting cosmic strings. We demonstrate, by using a solvable model of transonic strings, that the presence of a current leads to a suppression of the gravitational emission of cusps, kinks and different types of loops. We also show that, when a current is present, the spectrum of emission of loops with cusps is exponentially sup
