Abstract:The deflection and gravitational lensing of light and massive particles in arbitrary static, spherically symmetric and asymptotically (anti-)de Sitter spacetimes are considered in this work. We first proved that for spacetimes whose metric satisfying certain conditions, the deflection of null rays with fixed closest distance will not depend on the cosmological constant Λ, while that of timelike signals and the apparent angle in gravitational lensing still depend on Λ. A two-step perturbative method is then dev… Show more
