What the Sloan Digital Sky Survey V is up to

Time: 12:30 PM - 1:30 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: I'll describe what SDSS-V is observing these days. It uses two wide field robotic fiber positioners, one in New Mexico and one in Chile, to take near-infrared spectra (mostly of stars) and optical spectra (mostly of active galactic nuclei), mapping the Milky Way, observing radial velocity variations, observing quasar variability, and determining the masses of black holes out to high redshift (well, the highest redshifts at which such measurements have been made to date, up to about z=3 anyway). This year, a completely different set of SDSS telescopes came on line, which is a unique instrument conducting spatially continuous spectroscopy across thousands of square degrees of the Milky Way and observing nearby galaxies too.
