Feb 9 RLM 5.104	SPECIAL COLLOQUIUM Keith Hawkins Columbia University	Galactic Archaeology with Spectroscopy and Gaia One of the key objectives of modern astrophysics is to understand the formation and evolution galaxies. Dissecting the assembly history of the Milky Way, which is a fantastic testing ground for our theories of galaxy formation, requires a detailed mapping of the structure, dynamics, chemical composition, and age distribution of its stellar populations. We have entered an era of large spectroscopic and astrometric surveys, which has begun to pave the way for the exciting advancements in this field. Combining data from the many multi-object spectroscopic surveys, which are already underway, and the rich dataset from Gaia will undoubtedly be the way forward in order to disentangle the full chemo-dynamical history of our Galaxy. In this talk, I will discuss my current work in Galactic archaeology and how I have used large spectroscopic surveys to dissect the structure of our Galaxy. I will also explore the future of Galactic archaeology and discuss ways in which UT could position itself as a leader in this field. close
