Photon Orbital Angular Momentum in Astrophysics
arXiv:astro-ph/0307430 · doi:10.1086/378623
Abstract
Astronomical observations of the orbital angular momentum of photons, a property of electromagnetic radiation that has come to the fore in recent years, have apparently never been attempted. Here, I show that measurements of this property of photons have a number of astrophysical applications.
