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…
ConKer: evaluating isotropic correlations of arbitrary order
Zachery Brown, Gebri Mishtaku, Regina Demina
High order correlations in the cosmic matter density have become increasingly valuable in cosmological analyses. However, computing such correlation functions is computationally ex…
