Weak gravitational lensing in brane-worlds
arXiv:astro-ph/0602427
Abstract
We derive the deflection angle of light rays caused by a brane black hole with mass m and tidal charge q in the weak lensing approach, up to the second order in perturbation theory. We point out when the newly derived second order contributions become important.
