Determining the Hubble Constant without the Sound Horizon: Perspectives with Future Galaxy Surveys
Gerrit S. Farren, Oliver H. E. Philcox, Blake D. Sherwin
constraints from galaxy surveys are sourced by the geometric properties of two standardisable rulers: the sound horizon scale, , and the matter-radiation equality scale,…
Precision analysis of the redshift-space galaxy bispectrum
Mikhail M. Ivanov, Oliver H. E. Philcox, Takahiro Nishimichi +3
We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbat…
Cosmological constraints without fingers of God
Mikhail M. Ivanov, Oliver H. E. Philcox, Marko Simonović +3
Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as com…
Analytic Gaussian Covariance Matrices for Galaxy -Point Correlation Functions
Jiamin Hou, Robert N. Cahn, Oliver H. E. Philcox +1
We derive analytic covariance matrices for the -Point Correlation Functions (NPCFs) of galaxies in the Gaussian limit. Our results are given for arbitrary and projected onto…
A First Detection of the Connected 4-Point Correlation Function of Galaxies Using the BOSS CMASS Sample
Oliver H. E. Philcox, Jiamin Hou, Zachary Slepian
We present an detection of the non-Gaussian 4-Point Correlation Function (4PCF) using a sample of galaxies from the BOSS CMASS dataset. Our…
Cosmology Without Window Functions: Cubic Estimators for the Galaxy Bispectrum
Oliver H. E. Philcox
When analyzing the galaxy bispectrum measured from spectroscopic surveys, it is imperative to account for the effects of non-uniform survey geometry. Conventionally, this is done b…
