Magnification relations for Kerr lensing and testing Cosmic Censorship
M. C. Werner, A. O. Petters
A Kerr black hole with mass parameter m and angular momentum parameter a acting as a gravitational lens gives rise to two images in the weak field limit. We study the corresponding…
Light's Bending Angle due to Black Holes: From the Photon Sphere to Infinity
Savitri V. Iyer, Arlie O. Petters
The bending angle of light is a central quantity in the theory of gravitational lensing. We develop an analytical perturbation framework for calculating the bending angle of light…
Formalism for testing theories of gravity using lensing by compact objects. III: Braneworld gravity
Charles R. Keeton, A. O. Petters
Braneworld gravity is a model that endows physical space with an extra dimension. In the type II Randall-Sundrum braneworld gravity model, the extra dimension modifies the spacetim…
Formalism for testing theories of gravity using lensing by compact objects. II: Probing Post-Post-Newtonian metrics
Charles R. Keeton, A. O. Petters
We study gravitational lensing by compact objects in gravity theories that can be written in a Post-Post-Newtonian (PPN) framework: i.e., the metric is static and spherically symme…
Formalism for Testing Theories of Gravity Using Lensing by Compact Objects. I: Static, Spherically Symmetric Case
Charles R. Keeton, A. O. Petters
We are developing a general, unified, and rigorous analytical framework for using gravitational lensing by compact objects to test different theories of gravity beyond the weak-def…
