Angular Momentum on Galactic Scales: The Roles of Initial Conditions, Non-linear Evolution, and Randomness


In this talk we will go on a journey across cosmic time and follow the buildup of the angular momentum of galaxies and their host halos. Galactic angular momentum, which is a strong driver of galactic morphology, has its origins in the relatively simple linear growth phase of structure formation, but is also governed by complex non-linear processes. We will hence explore its relation to dark matter angular momentum, and the roles of baryonic physics and even of randomness in its evolution, while contrasting results from numerical simulations with analytical models.
