Measuring local primordial non-Gaussianity from the clustering of DESI DR1 LRGs and QSOs

Z. Brown, B. Levi, H. Randall +42

We report the first measurement of primordial non-Gaussianity (PNG), parameterized by , in the configuration space two-point correlation function (2pcf). We employ…

Local primordial non-Gaussianity using cross-correlations of DESI tracers

A. J. Rosado-Marín, A. J. Ross, H. Seo +46

We constrain local primordial non-Gaussianity by a combined analysis of auto and cross-correlations of DESI DR1 tracers, leveraging LRGs and QSOs as well as ELGs between $0.8<z<3.1…

First Detection of the Baryon Acoustic Oscillation (BAO) Feature in the 3-Point Correlation Function of DESI DR1 Luminous Red Galaxies

Farshad Kamalinejad, Zachary Slepian, Alex Krolewski +55

We present the first detection of the 3-Point Correlation Function (3PCF) Baryon Acoustic Oscillation (BAO) signal from the DESI Data Release 1 (DR1) sample of Luminous Red Galaxie…

The DESI DR1 Peculiar Velocity Survey: The Tully-Fisher Distance Catalog

K. Douglass, S. BenZvi, A. G. Kim +64

We calibrate the Tully-Fisher relation (TFR) using observations of spiral galaxies taken during the first year (DR1) of the DESI galaxy redshift survey. The rotational velocities o…

DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints

DESI Collaboration, M. Abdul-Karim, J. Aguilar +184

We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
