Title: Galactic Archaeology in the era of Large Surveys
Abstract: What are the processes that govern the formation evolution and assembly of galaxies across cosmic time? This question is among the most fundamental in modern astronomy yet the answer still eludes us to this day. The Milky Way is an optimal laboratory for answering the questions of galaxy formation and assembly because it is one of the only systems to date where we can obtain detailed and precise data on the positions motions and chemical composition for billions of individual stars. Using our Galaxy as a sandbox for exploring galaxy formation and assembly is the essence of Galactic archaeology. In this context, I will present my ongoing work in Galactic and stellar archaeology using large spectroscopic photometric and astrometric surveys together with high resolution spectroscopy. I aim to cover topics including chemical tagging, Galactic structure, metal-poor stars, and methods for using industrial-scale spectroscopic or astrometric surveys to carry out Galactic archaeology.
