Painlevé-Gullstrand-type coordinates for the five-dimensional Myers-Perry black hole
Tehani K. Finch
The Painleve-Gullstrand coordinates provide a convenient framework for presenting the Schwarzschild geometry because of their flat constant-time hypersurfaces, and the fact that th…
Coordinate families for the Schwarzschild geometry based on radial timelike geodesics
Tehani K. Finch
We explore the connections between various coordinate systems associated with observers moving inwardly along radial geodesics in the Schwarzschild geometry. Painlevé-Gullstrand (P…
Global Causal Structure of a Transient Black Object
Tehani K. Finch, James Lindesay
A singularity-free and spherically symmetric transient black object whose center remains always timelike, yet directly manifests a trapped region, has been constructed and numerica…
Analytic expressions for mean magnification by a quadrupole gravitational lens
Tehani K. Finch, Lisa P. Carlivati, Joshua N. Winn +1
We derive an analytic expression for the mean magnification due to strong gravitational lensing, using a simple lens model, a singular isothermal sphere embedded in an external she…
