Linking MW and Extragalactic Optical Spectroscopy with LVM

Connecting studies across the pc (sub-GMC) and kpc (galaxy-wide) scales is fundamental to understanding the physics governing star formation, the structure and energetics of the ISM, the baryon cycle, and ultimately, the evolution of galaxies. LVM in SDSS-V is taking the first step towards the “spectral panopticon”, a full spectroscopic image of the sky, providing optical IFU data-cubes to resolve, e.g., SF structures, GMCs, H II regions and young stellar clusters. LVM is covering the bulk of the southern MW disk at 0.1-1 pc resolution over about 1 steradian of sky, and the entire Magellanic Clouds at 10 pc resolution. I will present initial results comparing resolved to integrated views of Orion, in particular focusing on line ratio diagnostics and gas phase oxygen abundances. As MPIA and Harvard are both full members of SDSS-V, I will also provide an overview of the project and advertise opportunities to get involved.
