After placing local and distant galaxy abundances on a common scale, the authors find Milky Way high-alpha disc patterns at z~2-3, evidence for alpha-bimodality in M31, and place the MW and GSE on the z~3 mass-metallicity relation.

abstract
This proceeding overviews our current understanding of the orbital history and mass of the Large and Small Magellanic Clouds. Specifically I will argue that the Clouds are on their first infall about our Milky Way and that their total masses are necessarily ~10 times larger than traditionally estimated. This conclusion is based on the recently revised HST proper motions of the Clouds and arguments concerning the binary status of the LMC-SMC pair and their baryon fractions

ChemZz I: Comparing Oxygen and Iron Abundance Patterns in the Milky Way, the Local Group and Cosmic Noon
After placing local and distant galaxy abundances on a common scale, the authors find Milky Way high-alpha disc patterns at z~2-3, evidence for alpha-bimodality in M31, and place the MW and GSE on the z~3 mass-metallicity relation.
