Title: JWST Imaging of the Stellar Populations of Andromeda and Triangulum
Abstract: The James Webb Space Telescope is revolutionizing virtually all areas of observational astrophysics, and that includes our nearest galactic neighbors. I discuss imaging results of three guest observer programs (2301, 2609, 3322) toward Andromeda and Triangulum, aimed at elucidating the nature of their stellar populations: their metallicity distribution functions, their star formation histories, and their chemical evolution. We can now investigate, to superior detail than ever available before, the similarities and differences between these galaxies and our own, and thus we are witness to the birth extra-galactic archaeology.
