Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
M. Ishak, J. Pan, R. Calderon +68
We present cosmological constraints on deviations from general relativity (GR) from the first-year of clustering observations from Dark Energy Spectroscopic Instrument (DESI) in co…
An updated constraint on the Effective Field Theory of Dark Energy
Chi Zheng, Wei Liu, Zonghao Zhan +1
The Effective Field Theory of Dark Energy (EFTofDE) provides a systematic and model-independent framework to study dark energy (DE) and modified gravity (MG) with one additional sc…
Cosmological constraints from the Minkowski functionals of the BOSS CMASS galaxy sample
Wei Liu, Enrique Paillas, Carolina Cuesta-Lazaro +2
For the first time, we develop a simulation-based model for the Minkowski functionals (MFs) of large-scale structure, which allows us to extract the full information available from…
Probing massive neutrinos and modified gravity with redshift-space morphologies and anisotropies of large-scale structure
Wei Liu, Liang Wu, Francisco Villaescusa-Navarro +3
Strong degeneracy exists between some modified gravity (MG) models and massive neutrinos because the enhanced structure growth produced by modified gravity can be suppressed due to…
Forecasts on Anisotropic Cosmic Birefringence Constraints for CMB Experiment in the Northern Hemisphere
Yiwei Zhong, Hongbo Cai, Si-Yu Li +3
The study of cosmic birefringence through Cosmic Microwave Background (CMB) experiments is a key research area in cosmology and particle physics, providing a critical test for Lore…
