Explorations of Inflation and Dark Matter
Abstract: In this talk I discuss recent and ongoing work to understand the end of inflation and the nature of dark matter. I will start by discussing simulations of nonlinear structure formation during post-inflation reheating. I will then show how this early phase of the universe is analogous to axion-like dark matter. I will finish by discussing two lines of ongoing work with axion-like dark matter. First, using strong gravitational lensing to constrain ultralight dark matter. Second, developing new simulations of two-axion models.
