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.…
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…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: a multi-tracer analysis in Fourier space for measuring the cosmic structure growth and expansion rate
Gong-Bo Zhao, Yuting Wang, Atsushi Taruya +23
We perform a joint BAO and RSD analysis using the eBOSS DR16 LRG and ELG samples in the redshift range of , and detect a RSD signal from the cross power spectrum at…
