A Universal Framework for Horizon-Scale Tests of Gravity with Black Hole Shadows
Wentao Liu, Yang Liu, Di Wu +1
In this Letter, we have developed a numerically efficient framework for evaluating parameters in metric theories of gravity, and applied it to constrain the horizon-scale magnetic…

Lorentz violation signatures in the low-energy sector of Hořava gravity from black hole shadow observations
Wentao Liu, Hongxia Huang, Di Wu +1
In this paper, we use the Hořava gravity model and EHT observations of supermassive black holes (BHs) to investigate signatures of Lorentz violation in real astrophysical environme…
