Special Colloquium: "New Tools for Galactic Archaeology from the Milky Way"
One of the critical components for understanding galaxy evolution is understanding the Milky Way Galaxy itself -- its detailed structure and chemodynamical properties, as well as fundamental stellar physics, which we can only study in great detail locally. This field is currently undergoing a dramatic expansion to the kinds of large-scale statistical analyses long used by the extragalactic community, among others, thanks in part to the enormous influx of data from multiple large space- and ground-based surveys. I will describe the Milky Way and Local Group in the context of general galaxy evolution and highlight some recent developments in Galactic astrophysics that have strong implications for our understanding of how galaxies form and change across cosmic time. These advances include work I have done in characterizing different phases of the ISM, understanding stellar interiors via asteroseismology, describing the resolved bulk stellar properties of the inner disk and bulge, and mapping stellar chemical properties and star formation histories throughout the Galactic disk. The rapid progress in these areas promises to continue, with the advent of coming datasets from missions like Gaia, the GMT, and WFIRST.
