A Test for Cosmological Parity Violation Using the 3D Distribution of Galaxies
Robert N. Cahn, Zachary Slepian, Jiamin Hou
We show that the galaxy 4-Point Correlation Function (4PCF) can test for cosmological parity violation. The detection of cosmological parity violation would reflect previously unkn…
Analytic Gaussian Covariance Matrices for Galaxy -Point Correlation Functions
Jiamin Hou, Robert N. Cahn, Oliver H. E. Philcox +1
We derive analytic covariance matrices for the -Point Correlation Functions (NPCFs) of galaxies in the Gaussian limit. Our results are given for arbitrary and projected onto…
ENCORE: An Estimator for Galaxy -Point Correlation Functions
Oliver H. E. Philcox, Zachary Slepian, Jiamin Hou +3
We present a new algorithm for efficiently computing the -point correlation functions (NPCFs) of a 3D density field for arbitrary . This can be applied both to a discrete spe…
