Titel: First results from the GECKOS survey: what 36 of the Milky Way's closest cousins can tell us about our own Galaxy

Zusammenfassung: The Milky Way is the most well-studied galaxy in the Universe, though comparisons to its neighbours prove difficult, owing to our location embedded within its disc. One technique to overcome this challenge is the study of Milky Way analogues. I will present the GECKOS survey, a recent ESO VLT/MUSE large programme that observed 36 nearby Milky Way-mass disc galaxies hosting a range of star formation rates and structural morphologies. Importantly, this is the first such survey of edge-on galaxies, allowing us to observe these targets at the same geometry that we do the Milky Way. The extraordinary depth of GECKOS observations enables studies of faint, off-plane stellar populations, and an understanding of the diversity of assembly histories possible for galaxies that have accumulated the same amount of mass as our own. I will summarise GECKOS and its first results, including the use of stellar kinematics to define dynamical structures, stellar populations and assembly histories of said structures, galactic outflow science, and recent dynamical modelling efforts.
