With the dramatic increase in data, there is an opportunity to understand its limitations: how can this data actually inform our Galactic history? I will show some of the limitations (and opportunities) in using stellar spectra and derived element abundances for unravelling galactic history in the disk: 1 in 100 stars in high-resolution IR surveys of the disk are doppelgangers - identical but unrelated - impeding the prospect of so-called "chemical tagging" with these data. Furthermore, many individual element abundances can be predicted to a precision of ~0.015 dex, given only three measurements; two abundances, for elements produced in type Ia and II supernovae, and age Such limitations frame how we can most effectively work with the data, to turn photons into a quantified description of Galactic history. | 8 , HEP Journal Club (12:30 PM - 1:30 PM) Kevin Kelly, New Thoughts on an Old Anomaly (2:00 PM - 3:00 PM) + Abstract: | 9 (12:15 PM - 1:30 PM) , Equity & Inclusion Committee (12:30 PM - 2:00 PM) | 10 Lorenz Eberhardt, 3d Gravity and Teichmueller TQFT (2:00 PM - 3:00 PM) + Abstract: Zare (3:30 PM - 5:30 PM) |
