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…
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…
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…
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.…
Dynamical dark energy in light of cosmic distance measurements II: a study using current observations
Xiaoma Wang, Gan Gu, Xiaoyong Mu +2
We extract key information of dark energy from current observations of BAO, OHD and , and find hints of dynamical behaviour of dark energy. In particular, a dynamical dark ene…
Dynamical dark energy in light of cosmic distance measurements I: a demonstration using simulated datasets
Gan Gu, Xiaoma Wang, Xiaoyong Mu +2
We develop methods to extract key dark energy information from cosmic distance measurements including the BAO scales and supernovae luminosity distances. Demonstrated using simulat…
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…
A new consistency test for CDM cosmology using galaxy surveys
Jinglan Zheng, Gong-Bo Zhao, Yuting Wang +6
We propose a new consistency test for the CDM cosmology using baryonic acoustic oscillations (BAO) and redshift space distortion (RSD) measurements from galaxy redshift surveys.…
Extracting high-order cosmological information in galaxy surveys with power spectra
Yuting Wang, Gong-Bo Zhao, Kazuya Koyama +11
The reconstruction method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes…
