We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6240 RRLs out to ∼120 kpc from the Galactic center and over 12,000 individual epochs with homogeneously derived stellar atmospheric parameters. We int...

The Dark Energy Spectroscopic Instrument is conducting a redshift survey, mapping the universe in three dimensions to measure the history of cosmic expansion. As well as extragalactic objects, it is targeting millions of Milky Way stars, including white dwarfs. Using Data Release 1 we assemble the largest catalogue o...

The Tully-Fisher (TF) relation is an empirical tool for estimating distances to spiral galaxies. Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity (PV) Survey uses photometric position angles (PAs) to place its fibers along the semi-major axis of the galaxy and infer maximum rotational velocities for ≈ 53,0...
