Environmental screening of dark matter haloes in gravity
Difu Shi, Baojiu Li, Jiaxin Han
In certain theories of modified gravity, solar system constraints on deviations from general relativity (GR) are satisfied by virtue of a so-called screening mechanism, which enabl…

Can we distinguish early dark energy from a cosmological constant?
Difu Shi, Carlton M. Baugh
Early dark energy (EDE) models are a class of quintessence dark energy with a dynamically evolving scalar field which display a small but non-negligible amount of dark energy at th…

Exploring the liminality: properties of haloes and subhaloes in borderline gravity
Difu Shi, Baojiu Li, Jiaxin Han +2
We investigate the properties of dark matter haloes and subhaloes in an gravity model with , using a very high-resolution N-body simulation. The model is a…
