Asymmetric Light Bending in the Equatorial Kerr Metric
Arthur B. Congdon, Savitri V. Iyer, Charles R. Keeton
The observation of the bending of light by mass, now known as gravitational lensing, was key in establishing general relativity as one of the pillars of modern physics. In the past…
Frame-dragging induced asymmetry in the bending of light near a Kerr black hole
S. V. Iyer
The deflection of light's trajectory has been studied in many different spacetime geometries in weak and strong gravity, including the special cases of spherically symmetric static…
Strong and Weak Deflection of Light in the Equatorial Plane of a Kerr Black Hole
Savitri V. Iyer, Edward C. Hansen
Analytical series expansions for the bending of light in the equatorial plane of a Kerr black hole are presented in both the strong and weak deflection regimes. It is critical that…
Light's Bending Angle in the Equatorial Plane of a Kerr Black Hole
Savitri V. Iyer, Edward C. Hansen
We present here a detailed derivation of an explicit spin-dependent expression for the bending angle of light as it traverses in the equatorial plane of a spinning black hole. We s…
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…
The Vacuum Einstein Equations via Holonomy around Closed Loops on Characteristic Surfaces
Savitri V. Iyer, Carlos N. Kozameh, Ezra T. Newman
We reformulate the standard local equations of general relativity for asymptotically flat spacetimes in terms of two non-local quantities, the holonomy around certain closed nu…
