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…

Analytical Template for the 4-Point Correlation Function Covariance Beyond the Gaussian Random Field : 1-Loop Corrections with Third-Order Densities
William Ortolá Leonard, Zachary Slepian
Analytical templates for the 4-Point Correlation Function (4PCF) covariance matrix have been developed in the past assuming a Gaussian Random Field (GRF). In this work, we present…
