Description:

Galaxy formation is a core science driver of the majority of current and upcoming astronomical facilities. Astrophysicists want to know how galaxy populations emerged from the Big Bang, as well as how stars and massive black holes formed in galaxies. For cosmologists, understanding galaxy formation is necessary to model how baryonic processes affect measurements of dark matter and dark energy. Owing to the extreme dynamic range of galaxy formation, advances are driven by combining insights from large-scale numerical simulations, analytic modeling, and observations. In this colloquium, I will give an overview of the research done in the galaxy formation group at Northwestern, which aims to model all the main physical processes driving galaxy formation. I will highlight some recent predictions from our state-of-the-art numerical simulations, ranging from the origins of stellar baryons, to the growth of supermassive black holes, to energetic black hole-driven outflows. Our simulations have revealed many unexpected surprises, which have opened new lines of investigation.
