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
