Topological Defects
Description
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 phenomenology, including a search for them using recent Pulsar Timing Array data from NANOGrav and IPTA.
