"DESI" The Largest ever 3D Map of the Universe

Guest Speaker

Thursday, 17th September 2020 (19:45 - 22:00)

Venue: Virtual Meeting

The Dark Energy Spectroscopic Instrument (DESI) is a newly installed spectrograph at Kitt Peak National Observatory’s 4-meter Mayall telescope. DESI is capable of obtaining five thousand star and galaxy spectra simultaneously, and over the next five years will create the largest ever three-dimensional of the Universe. This talk will explain the scientific motivation for DESI, highlight some of our ambitious efforts that have made DESI possible, and describe how DESI is capable of mapping the Universe ten times better than ever before.
