Lowering the strong coupling mode of modified teleparallel gravity theories
Yu-Min Hu, Bi-Chu Li, Yang Yu +3
We investigate the strong coupling problem in modified teleparallel gravity theories using the effective field theory (EFT) approach, demonstrating that it is possible to shift the…
Observational test for gravity with weak gravitational lensing
Qingqing Wang, Xin Ren, Yi-Fu Cai +2
In this article we confront a class of gravity models with observational data of galaxy-galaxy lensing. Specifically, we consider the gravity models containing a smal…
Quintom cosmology and modified gravity after DESI 2024
Yuhang Yang, Xin Ren, Qingqing Wang +4
We reconstruct the cosmological background evolution under the scenario of dynamical dark energy through the Gaussian process approach, using the latest Dark Energy Spectroscopic I…
Data reconstruction of the dynamical connection function in cosmology
Yuhang Yang, Xin Ren, Bo Wang +2
We employ Hubble data and Gaussian Processes in order to reconstruct the dynamical connection function in cosmology beyond the coincident gauge. In particular, there exist t…
Can we constrain warm dark matter masses with individual galaxies?
Shurui Lin, Francisco Villaescusa-Navarro, Jonah Rose +9
We study the impact of warm dark matter mass on the internal properties of individual galaxies using a large suite of 1,024 state-of-the-art cosmological hydrodynamic simulations f…
Exploring Gravity via strongly lensed fast radio bursts
Xinyue Jiang, Xin Ren, Zhao Li +2
This study aims to investigate the strong gravitational lensing effects in gravity. We present the theoretical analytic expressions for the lensing effects in gravity…
