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…
Increasing the sensitivity of full-shape galaxy clustering measurements in configuration-space with three-point statistics
Zachery Brown, Lado Samushia
We investigate the cosmological constraining power of a compressed line of sight dependent three point correlation function (3PCF) estimator on small scales (<80 Mpc/h) in configur…
Bounding the Effect of HOD Assumptions on Small-Scale Clustering Constraints
Nick Magnelli, Zachery Brown, Lado Samushia
Small-scale galaxy clustering is expected to contain substantial cosmological information, but the extent to which this information constrains halo-based cosmologies independent of…
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…
Constraining primordial non-Gaussianity from the large scale structure two-point and three-point correlation functions
Z. Brown, R. Demina, A. G. Adame +47
Surveys of cosmological large-scale structure (LSS) are sensitive to the presence of local primordial non-Gaussianity (PNG), and may be used to constrain models of inflation. Local…
