Self-lensing of a Singular Isothermal Sphere
arXiv:astro-ph/9907020 · doi:10.1103/PhysRevD.61.123002
Abstract
Many astrophysical systems can be approximated as isothermal spheres. In an isothermal sphere, the ``foreground'' objects can act as lenses on ``background'' objects in the same distribution. We study gravitational lensing by a singular isothermal sphere analytically. Our results may have interesting applications.
