Static Microlensing: Concept, Method and Candidates
Qi Guo, Leyao Wei, Wentao Luo +6
We propose a novel microlensing event search method that differs from either the traditional time domain method, astrometric microlensing, or the parallax microlensing method. Our…
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…
Testing Cotton gravity as dark matter substitute with weak lensing
Geyu Mo, Qingqing Wang, Xin Ren +3
Harada proposed a modified theory of gravity called Cotton gravity, and argued that it successfully explains the rotation curves of galaxies without the need of dark matter. I…
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…
Black-Hole-to-Halo Mass Relation From UNIONS Weak Lensing
Qinxun Li, Martin Kilbinger, Wentao Luo +17
This letter presents, for the first time, direct constraints on the black-hole-to-halo-mass relation using weak gravitational lensing measurements. We construct type I and type II…
