Null geodesics, quasinormal modes, and the correspondence with shadows in high-dimensional Einstein-Yang-Mills spacetimes

Abstract: Null geodesics, quasinormal modes of a massless scalar field perturbation, and the correspondence with shadow radii are investigated in the background spacetime of high-dimensional Einstein-Yang-Mills black holes. Based on the properties of null geodesics, we obtain the connection between the radius of a photon sphere and the radius of a horizon in the five-and six-dimensional Einstein-Yang-Mills spacetimes. Especially in the five-dimensional case, there exist two branches for the radius of a photon sphere, bu… Show more

“…This work is helpful to detect indirectly the dark matter near the event horizon. Subsequently, this correspondence was verified by the 3rd order WKB approximation approach in [54,55] and by the 13th order WKB approximation approach in [56], respectively.…”

“…In this work, we obtain a black hole (BH) solution in the 4D EGB gravity coupled with nonlinear electrodynamics (NED) proposed in [40] in the framework of [36][37][38] theory. Quasinormal modes, deflection angle, shadows of BHs, and Hawking radiation were studied in [41][42][43][44][45][46][47]. The image of the M87* BH, observed by collaboration with the Event Horizon Telescope [48], confirms the existence of BHs in the universe.…”
