Local Volume Mapper
The Local Volume Mapper (LVM) is an integral-field spectroscopic survey, targeting the Milky Way, Small and Large Magellanic Clouds, M31, and other Local Volume galaxies. LVM will make use of newly built spectrographs that will cover a large wavelength range of 3600 – 10000 Å, with spectral resolution R ~ 4000. It will collect more than 25 million contiguous spectra over 3,000 square degrees of sky. LVM will make most of its observations using newly acquired smaller telescopes (0.16 – 1m), that will be located at Apache Point and Las Campanas Observatories.
Galaxy formation can be seen as a self-regulating process, with energy exchange between stars and interstellar gas occurring at numerous points, both spatially and temporary. LVM will spectroscopically map the global interstellar medium of the Milky Way and Local Group galaxies, with unprecedented spatial resolution: reaching 0.1-1 pc resolution in the Milky Way, 10 pc resolution in the Magellanic Clouds, up to 20 – 100 pc resolution out to distances at 5 Mpc. This makes the LVM uniquely positioned to study the star formation and physics of the interstellar medium in great detail, being able to distinguish individual star formation knots and the filamentary structures and shock networks between them. LVM will be able to connect studies across the parsec (sub Giant Molecular Cloud) and kilo-parsec (galaxy-wide) scales, which is fundamental to understand the physics governing star formation, the structure of the interstellar medium, the baryon cycle, and ultimately, the evolution of galaxies.
