Probing Observable Features of Lorentz violation in Low-Energy HoÅava Gravity with Accretion Disk Images of Black Hole
Meng-Die Zhao, Yu-Yan Wang, Ke-Jian He +1
In this paper, we study the observable signatures of Lorentz violation (LV) in low-energy Horava gravity by simulating the images and polarization features of rotating LV black hol…
