Precision Redshift-Space Galaxy Power Spectra using Zel'dovich Control Variates
Joseph DeRose, Shi-Fan Chen, Nickolas Kokron +1
Numerical simulations in cosmology require trade-offs between volume, resolution and run-time that limit the volume of the Universe that can be simulated, leading to sample varianc…
Accurate predictions from small boxes: variance suppression via the Zel'dovich approximation
Nickolas Kokron, Shi-Fan Chen, Martin White +2
Simulations have become an indispensable tool for accurate modelling of observables measured in galaxy surveys, but can be expensive if very large dynamic range in scale is require…
Optical depth to reionization from perturbative 21cm clustering
Noah Sailer, Shi-Fan Chen, Martin White
The optical depth is the least well determined parameter in the standard model of cosmology, and one whose precise value is important for both understanding reionization and fo…
Cosmological Analysis of Three-Dimensional BOSS Galaxy Clustering and Planck CMB Lensing Cross Correlations via Lagrangian Perturbation Theory
Shi-Fan Chen, Martin White, Joseph DeRose +1
We present a formalism for jointly fitting pre- and post-reconstruction redshift-space clustering (RSD) and baryon acoustic oscillations (BAO) plus gravitational lensing (of the CM…
