Chemical Mapping of the Milky Way

Abstract: One of the most intriguing questions of astronomy is how our Galaxy formed and evolved during its nearly 13 billion year lifetime. Answering this question is possible only by studying the chemical composition of all the sub-systems of the Milky Way, the thin and thick disk, and the Galactic bulge and halo. Our goal is to create the largest chemical map of the Milky Way to date and use this information to uncover the history of our Galaxy. We wish to achieve this goal through a robust science project using both private and public data from the Milky Way Mapper (MWM) high-resolution spectroscopic survey part of the 5th iteration of the Sloan Digital Sky Survey (SDSS-V). PI Mészáros is the abundance working group leader within the team of MWM until the end of the SDSS-V project in 2025. MWM will observe nearly 5 million stars and will derive accurate atmospheric parameters and chemical abundances for all them allowing the mapping of our Milky Way in unprecedented detail.
