Measurement of Parity-Violating Modes of the Dark Energy Spectroscopic Instrument (DESI) Year 1 Luminous Red Galaxies' 4-Point Correlation Function
Zachary Slepian, Alex Krolewski, Alessandro Greco +38
Here we report the first measurement of the parity-violating (PV) 4-Point Correlation Function (4PCF) of the Dark Energy Spectroscopic Instrument's Year 1 Luminous Red Galaxy (DESI…

Power Spectrum, Bispectrum, 2- and 3-Point Correlation Function, and Beyond
Zachary Slepian, Farshad Kamalinejad, Alessandro Greco
N-Point Correlation Functions, usually with N = 2, 3, and their Fourier-space analogs power spectrum and bispectrum, are major tools used in cosmology to capture the clustering of…

From Theory to Forecast: Neutrino Mass Effects on Mode-Coupling Kernels and Their Observational Implications
Farshad Kamalinejad, Zachary Slepian
We present an analytical expression that gives both the matter and tracer (halo or galaxy) power spectrum with 1-loop corrections that include the neutrino effects on the mode coup…
