Probing Parity Violation with Weak Lensing Trispectrum
Sijin Chen, Zhengyangguang Gong, Jiamin Hou
We establish the weak gravitational lensing convergence trispectrum as an independent probe of cosmological parity violation in the late-time Large-Scale Structure (LSS). To map th…
CMB Lensing Trispectrum as a Probe of Parity Violation in LSS
Alessandro Greco, Zachary Slepian, Jiamin Hou +1
We show that the Cosmic Microwave Background (CMB) lensing trispectrum is sensitive to parity violation in Large-Scale Structure (LSS). We obtain a compact expression for the reduc…
First Measurements of the 4-Point Correlation Function of Magnetohydrodynamic Turbulence as a Novel Probe of the Interstellar Medium
Victoria Williamson, James Sunseri, Zachary Slepian +2
In the Interstellar Medium (ISM), gas and dust evolve under magnetohydrodynamic (MHD) turbulence. This produces dense, non-linear structures that then seed star formation. Observat…
Full Parity-Violating Trispectrum in Axion Inflation: Reduction to Low-D Integrals
Matthew Reinhard, Zachary Slepian, Jiamin Hou +1
Recent measurements of the galaxy 4-Point Correlation Function (4PCF) have seemingly detected non-zero parity-odd modes at high significance. Since gravity, the primary driver of g…
Can Baryon Acoustic Oscillations Illuminate the Parity-Violating Galaxy 4PCF?
Jiamin Hou, Zachary Slepian, Drew Jamieson
Measurements of the galaxy 4-Point Correlation Function (4PCF) from theSloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey (SDSS BOSS) have recently found strong stati…
Parity-Odd Power Spectra: Concise Statistics for Cosmological Parity Violation
Drew Jamieson, Angelo Caravano, Jiamin Hou +2
We introduce the Parity-Odd Power (POP) spectra, a novel set of observables for probing parity violation in cosmological -point statistics. POP spectra are derived from composit…
On a Generating Function for the Isotropic Basis Functions and Other Connected Results
Zachary Slepian, Jessica Chellino, Jiamin Hou
Recently isotropic basis functions of unit vector arguments were presented; these are of significant use in measuring the N-Point Correlation Functions (NPCFs) of galaxy cluste…
A Model for the Redshift-Space Galaxy 4-Point Correlation Function
William Ortolá Leonard, Zachary Slepian, Jiamin Hou
The field of cosmology is entering an epoch of unparalleled wealth of observational data thanks to galaxy surveys such as DESI, Euclid, and Roman. Therefore, it is essential to hav…
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…
