The DESI Peculiar Velocity Survey

The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey is a secondary targeting program of the DESI main survey designed to systematically measure peculiar motion at z < 0.2. The Peculiar Velocity (PV) Survey combines the spectroscopic galaxy redshifts recorded by DESI with standardizable distance measurements from elliptical and spiral galaxies in the DESI Bright Galaxy Survey (BGS). Over the next few years, the DESI PV Survey will produce the largest catalog of peculiar velocities ever assembled, comprising more than 400,000 Fundamental Plane distances of elliptical galaxies in the BGS and more than 125,000 Tully-Fisher distances of disc galaxies in the Siena Galaxy Atlas. These measurements will offer a unique perspective on the mass and motions in the low redshift Universe and allow precision tests of gravity and dark energy. We describe the target selection of the PV survey and present preliminary results recorded during the first year of DESI observations.
