SDSSV_schematic_v15
SDSS-V will be carried out in both hemispheres, at Apache Point Observatory (APO) in the USA and Las Campanas Observatory (LCO) in Chile. Multi-object fiber spectroscopy will be obtained with two 2.5m telescopes, each feeding a near-infrared APOGEE spectrograph and an optical BOSS spectrograph, for the Milky Way Mapper and Black Hole Mapper programs. The Local Volume Mapper will make use of smaller telescopes at APO and LCO to perform its optical integral-field spectroscopy.
mastargaia_extcorr_RB20181127-mr_gi
Extinction-corrected color-luminosity diagram for the DR15 version of the MaStar Library, color-coded by metallicity (click to enlarge). The photometry in this figure are in SDSS bands. The derivation of the absolute magnitudes are based on distances computed by Bailer-Jones et al. (2018) using parallax from Gaia DR2.

Stacked quasar spectra
Stacked spectra of more than 46,000 quasars from the SDSS; each spectrum has been converted to a single horizontal line, and they are stacked one above the other with the closest quasars at the bottom and the most distant quasars at the top.
