Cosmological inference from the eBOSS QSO full-shape analysis with optimal redshift weights
Xiaoyong Mu, Zhuo-Heng Li, Wentao Luo +2
We present a full-shape power-spectrum analysis of the eBOSS DR16 quasar sample with optimal redshift weights. The DR16 QSO catalog contains 343,708 quasars over , a red…
A multitracer analysis for the eBOSS galaxy sample based on the effective field theory of large-scale structure
Ruiyang Zhao, Xiaoyong Mu, Rafaela Gsponer +8
We perform a multitracer full-shape analysis in Fourier space based on the effective field theory of large-scale structure (EFTofLSS) using the complete Sloan Digital Sky Survey IV…
Efficient estimators for power spectrum and bispectrum multipole measurements
Yunchen Xie, Ruiyang Zhao, Gan Gu +6
Large galaxy surveys demand fast and scalable estimators for anisotropic clustering statistics beyond the monopole. We present a suite of efficient FFT-based estimators for power-s…
Measuring the redshift-space distortions by cross-correlating the density fields before and after reconstruction
Weibing Zhang, Ruiyang Zhao, Xiaoyong Mu +4
In this work, we develop a theoretical model for the cross-power spectrum of the galaxy density field before and after standard baryonic acoustic oscillation (BAO) reconstruction.…
A cosmological full-shape power spectra analysis using pre- and post-reconstructed density fields
Weibing Zhang, Ruiyang Zhao, Xiaoyong Mu +4
In this work, we investigate a joint fitting approach based on theoretical models of power spectra associated with density-field reconstruction. Specifically, we consider the matte…
