|Abstract: The modern era of particle phenomenology increasingly looks to the cosmos and the early universe for hints of high-scale physics Beyond the Standard Model. In these regimes, many of the best-motivated candidates for new physics and their signals emerge through nonlinear and nonperturbative dynamics that require large-scale numerical simulations to make sharp predictions that guide experimental and observational efforts. In this work, I will discuss two applications of large-scale computing to BSM cosmology: the simulation of topological defects in the axion field for predictions of the axion dark matter mass; and calculations of gravitational wave production in the nonlinear regime of early matter dominated cosmologies that could be detected with current or future observatories.
