Microlensing of non-singular black holes at finite size: a ray tracing approach
Jens Boos, Hao Hu
We study the gravitational microlensing of various static and spherically symmetric non-singular black holes (and horizonless, non-singular compact objects of similar size). For po…

Quasinormal Modes and Dynamical Evolution of Scalar Fields in the Einstein-Bumblebee Theory with a Cosmological Constant
Hao Hu, Guoxiong Zhu
This paper investigates the dynamic behavior of static, spherically symmetric black holes within the Einstein-Bumblebee gravity model with a cosmological constant, focusing on scal…

Forced non-conformal relativistic fluid from the Chamblin-Reall gravity
Chao Wu, Hao Hu, Ruohan Wang +1
The Chamblin-Reall gravity is a remarkable non-conformal platform for the fluid/gravity correspondence to achieve its maximum efficiency. When a probe scalar field that does not ch…
