One latent to fit them all: a unified representation of baryonic feedback on matter distribution
Shurui Lin, Yin Li, Shy Genel +4
Accurate and parsimonious quantification of baryonic feedback on matter distribution is of crucial importance for understanding both cosmology and galaxy formation from observation…
Stochastic lensing of stars by ultralight dark matter halos
Andrew Eberhardt, Elisa Ferreira, Wentao Luo +2
Ultralight dark matter is an interesting dark matter candidate describing the lightest end of the mass parameter space. This model produces an oscillating granular pattern in halo…
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…
Point-Spread Function errors for weak lensing - density cross-correlations. Application to UNIONS
Ziwen Zhang, Martin Kilbinger, Fabian Hervas Peters +8
Aims:Calibrating the point spread function (PSF) is a fundamental part of weak gravitational lensing analyses. Even with corrected galaxy images, imperfect calibrations can introdu…
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…
