Abstract: In this paper, under the illumination of thin disk accretion, we have employed the ray-tracing method to carefully investigate shadows and rings of the Kehagias-Sfetsos(KS) black hole in deformed HoĊ™ava-Lifshitz(HL) gravity. The results show that… read more here.

DOI: 10.1103/physrevd.105.023024

Abstract: The feature of the observed shadows and rings of an astrophysical black hole (BH) may depend on its accretion flows and magnetic charge. We find that the shadow radii and critical impact parameters of the… read more here.
