Particle dynamics, black hole shadow and weak gravitational lensing in the f (Q) theory of gravity

Abstract

Abstract We study the particle dynamics around a black hole (BH) in f(Q) gravity. First, we investigate the influence of the parameters of f(Q) gravity on the horizon structure of the BH, photon orbits and the radius of the innermost stable circular orbit (ISCO) of massive particles. We further study the effects of the parameters of  f(Q) gravity on the shadow cast by the BH. Moreover, we consider weak gravitational lensing using the general method, where we also explore the deflection angle of light rays around the BH in  f(Q) gravity in uniform and nonuniform plasma mediums.
