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.
