Background-dependent and classical correspondences between and gravity
Cheng Wu, Xin Ren, Yuhang Yang +2
and gravity are based on fundamentally different geometric frameworks, yet they exhibit many similar properties. This article provides a comprehensive summary and com…
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…
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…
