Probing Parity Violation with Weak Lensing Trispectrum
Sijin Chen, Zhengyangguang Gong, Jiamin Hou
The paper develops a framework to use the weak lensing convergence trispectrum as a probe of cosmological parity violation, deriving projection formulas, evaluating parity‑odd temp…
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…
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…
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…
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…
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…
