Título: "Pushing the Analogy: Schawarzschild and Kerr Black Holes as Gravitational Lenses"
Ponente: Dr. Omar López-Cruz - Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE)
Resumen:
I present a study of the behavior of light before Schwarzschild and Kerr Black Holes. Gravitational lensing away from the black hole can be reproduced using axicones. Is it possible to pursue an optical analogy to reproduce orbiting light as seen in the proximity of a Schawarschild black hole? Is it possible to modify the trajectory of a ray and mimic frame dragging as in a Kerr black hole? With a generalized least-action approach, we show that a gradient index medium (GRIN) can reproduce the behavior in the proximity of Schwarzschild or Kerr black holes. We comment on some practical applications of our approach.
