Mapping the Nearby Universe: Insights from SDSS-V's Local Volume Mapper and the Road to SDSS-VI
The SDSS-V Local Volume Mapper (LVM) is providing key data to understand internal galactic processes and their impact on large-scale galactic dynamics through optical IFU spectroscopy mapping of vast areas of the Milky Way and nearby galaxies such as the Magellanic Clouds. With unprecedented spatial coverage (thousands of deg²), high physical resolution (<1 pc in the Milky Way, ~10 pc in the Magellanic Clouds), and a broad spectral range (3600–9800 Å), LVM bridges the gap between detailed, spatially resolved studies of stellar populations, H II regions, supernova remnants, and diffuse ionized gas, and lower-resolution extragalactic surveys like CALIFA or MaNGA. Looking ahead to SDSS-VI, an international collaboration—led in part by researchers from UNAM—aims to extend this high-resolution mapping to additional Local Group galaxies and to obtain deeper observations of faint emission lines in Galactic nebulae. This effort will be carried out through a dual-hemisphere strategy involving the existing LVM-I South facility at Las Campanas Observatory and a new northern IFU instrument (LVM-I North) on a 2-meter-class telescope. Together, these instruments will offer a transformative, comprehensive view of the interstellar medium under a wide range of conditions. These data will enable in-depth studies of stellar feedback, star formation, chemical enrichment, and the complex interactions among stars, gas, and dust across multiple spatial scales and environments. UNAM plays a central role in this institutional project, with privileged access to its unique dataset. This talk will present recent LVM results, data access methods, the historical impact of SDSS at UNAM, and the leadership opportunities ahead in SDSS-VI.
