Relativistic images of Schwarzschild black hole lensing
K. S. Virbhadra
We model massive dark objects at centers of many galaxies as Schwarzschild black hole lenses and study gravitational lensing by them in detail. We show that the ratio of mass of a…
Time delay and magnification centroid due to gravitational lensing by black holes and naked singularities
K. S. Virbhadra, C. R. Keeton
We model the massive dark object at the center of the Galaxy as a Schwarzschild black hole as well as Janis-Newman-Winicour naked singularities, characterized by the mass and scala…
Energy Distribution of a Charged Black Hole with a Minimally Coupled Scalar Field
Paul Halpern
Using three different energy-momentum complexes, the Einstein, Landau-Lifshitz, and Papapetrou prescriptions, we calculate the energy of an electrically charged black hole exact so…
Energy of the Taub Cosmological Solution
Paul Halpern
We calculate the total energy of Taub's 1951 exact solution for a Bianchi type IX geometry using several different energy-localization procedures, including the prescriptions of Ei…
