Gravitational Lensing from a Spacetime Perspective - http://relativity.livingreviews.org/Articles/lrr-2004-9/index.html
Article by Volker Perlick (Technical University, Berlin) published in Living Reviews in Relativity about gravitational lensing in curved spacetime (as opposed to descriptions that rely on slight relativistic deviations from the Newtonian-Euclidean description of gravity and space). |
