Computing the Small-Scale Galaxy Power Spectrum and Bispectrum in Configuration-Space
Oliver H. E. Philcox, Daniel J. Eisenstein
We present a new class of estimators for computing small-scale power spectra and bispectra in configuration-space via weighted pair- and triple-counts, with no explicit use of Four…
Inferring Galactic Parameters from Chemical Abundances: A Multi-Star Approach
Oliver Henry Edward Philcox, Jan Rybizki
Constraining parameters such as the initial mass function high-mass slope and the frequency of type Ia supernovae is of critical importance in the ongoing quest to understand galac…
Estimating Covariance Matrices for Two- and Three-Point Correlation Function Moments in Arbitrary Survey Geometries
Oliver H. E. Philcox, Daniel J. Eisenstein
We present configuration-space estimators for the auto- and cross-covariance of two- and three-point correlation functions (2PCF and 3PCF) in general survey geometries. These are d…
RascalC: A Jackknife Approach to Estimating Single and Multi-Tracer Galaxy Covariance Matrices
Oliver H. E. Philcox, Daniel J. Eisenstein, Ross O'Connell +1
To make use of clustering statistics from large cosmological surveys, accurate and precise covariance matrices are needed. We present a new code to estimate large scale galaxy two-…
