SDSS-V
• 5-year program beginning
mid-2020 in both
hemispheres
• 3 Science Programs:
• Milky Way Mapper,
Black Hole Mapper,
Local Volume Mapper
• 2 hemispheres: high-res
IR spectra, moderate-res
optical spectra + O
echelle, massively
multiplexed wide-field IFU

NSF DOES NOT DIRECTLY SUPPORT SDSS-IV or
SDSS-V! THAT IS WRONG!

Chemical tagging —> large sample size
Pairs of birth sibling stars are rare, but the number of such pairs in a
survey of sample size N, will scale as N2!!!!

SDSS-V will tell us which Milky Way we live in!THE MAKING OF THE MILKY WAY:
GALACTIC GENESIS
Exploiting advances in Data Science from SDSS-IV and stellar
physics from time-domain surveys (e.g. asteroseismology, TDA)

Very High-spatial-resolution (1-50pc) integral field spectroscopy of nearby galaxies
including the MW, M31, M33, and the Magellanic Clouds, with a major investment in
new DESI-style optical spectrographs to enable two 1600-fiber integral field units
(one in each hemisphere)

• M42 0.07 pc / spaxel
• APOGEE stars (yellow)
• Combine information from
gas and stars to map the
interaction between stars
and ISM
• Have Teff, L, Z, [X/H], fuv,
(age) for each star
• Gas: temperature, density,
kinematics, abundances
