The SDSS-V Local Volume Mapper (LVM)
I will present the SDSS-V Local Volume Mapper (LVM), a new facility and survey at Las Campanas Observatory that will produce the first optical spectroscopic data-cube of the Milky Way plane and the Magellanic Clouds. With its superb spatial resolution (sub-pc in the MW and ~10 pc in the LMC/SMC) the LVM will resolve the interface between the ionized ISM and individual sources of metals, ionization, and feedback. The LVM medium-resolution spectral coverage of the full optical window produces spatially resolved line and line-ratio maps for complete ionized nebulae (HII regions, SNRs, and PNe) and their surroundings, allowing for the characterization of their detailed internal chemical and thermo-dynamical structure. Permitting detailed studies of the star-formation, feedback, and chemical enrichment processes that drive galaxy evolution from the small scales in which metals and energy are injected, out to galactic scales.The LVM spatially resolved spectral mapping of large numbers of ionized nebulae across different environments promises to directly quantify the physical process that give rise to the abundance discrepancy problem and the large systematic errors that currently plague nebular abundance diagnostics.
