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…

Beyond the two-point correlation: constraining primordial non-gaussianity with density perturbation moments
Ethan Vislosky, Zachery Brown, Regina Demina +1
Constraining primordial non-Gaussianities (PNGs) in the large-scale cosmic structure (LSS) is an important step in understanding properties of the early universe, specifically in d…

DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
