Cosmological constraints on early dark energy from the full shape analysis of eBOSS DR16
Rafaela Gsponer, Ruiyang Zhao, Jamie Donald-McCann +5
We evaluate the effectiveness of Early Dark Energy (EDE) in addressing the Hubble tension using data from the completed eBOSS survey, focusing on luminous red galaxies (LRGs), quas…
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…
Analysis of Unified Galaxy Power Spectrum Multipole Measurements
Jamie Donald-McCann, Rafaela Gsponer, Ruiyang Zhao +2
We present a series of full-shape analyses of galaxy power spectrum multipole measurements from the 6dFGS, BOSS, and eBOSS galaxy surveys. We use an emulated effective field theory…
