Neural Network Acceleration of Large-scale Structure Theory Calculations
Joseph DeRose, Shi-Fan Chen, Martin White +1
We make use of neural networks to accelerate the calculation of power spectra required for the analysis of galaxy clustering and weak gravitational lensing data. For modern perturb…
Priors on red galaxy stochasticity from hybrid effective field theory
Nickolas Kokron, Joseph DeRose, Shi-Fan Chen +2
We investigate the stochastic properties of typical red galaxy samples in a controlled numerical environment. We use Halo Occupation Distribution (HOD) modelling to create mock rea…
Cosmological constraints from the tomographic cross-correlation of DESI Luminous Red Galaxies and Planck CMB lensing
Martin White, Rongpu Zhou, Joseph DeRose +15
We use luminous red galaxies selected from the imaging surveys that are being used for targeting by the Dark Energy Spectroscopic Instrument (DESI) in combination with CMB lensing…
A new analysis of galaxy 2-point functions in the BOSS survey, including full-shape information and post-reconstruction BAO
Shi-Fan Chen, Zvonimir Vlah, Martin White
We present a new method for consistent, joint analysis of the pre- and post-reconstruction two-point functions of the BOSS survey. The post-reconstruction correlation function is u…
The Ly forest flux correlation function: a perturbation theory perspective
Shi-Fan Chen, Zvonimir Vlah, Martin White
The Ly forest provides one of the best means of mapping large-scale structure at high redshift, including our tightest constraint on the distance-redshift relation before cosmic…
The cosmology dependence of galaxy clustering and lensing from a hybrid -body-perturbation theory model
Nickolas Kokron, Joseph DeRose, Shi-Fan Chen +2
We implement a model for the two-point statistics of biased tracers that combines dark matter dynamics from -body simulations with an analytic Lagrangian bias expansion. Using A…
