Gravitational waves from domain wall collapse, and application to nanohertz signals with QCD-coupled axions

We study for the first time the gravitational waves generated during the collapse of domain walls, incorporating the potential bias in the lattice simulations. The final stages of domain wall collapse are crucial for the production of gravitational waves, but have remained unexplored due to computat...
