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...

We present the largest statistical spectroscopic sample of radio quasars at 4.7<z<6.7 to date. These have been selected from a dedicated Dark Energy Survey Instrument (DESI) target program and provide a robust sample to study the influence of radio jets on early quasar evolution. Using low-frequency radio data from the...

We improve upon previous efforts to optimally combine overlapping galaxy samples in the DESI baryon acoustic oscillation analysis. By weighting each galaxy by its linear bias, overlapping galaxies are combined into a single, unified catalog, naturally avoiding double counting of cosmic volume and including all auto- an...
