Astronomical observations of the orbital angular momentum of photons, aproperty of electromagnetic radiation that has come to the fore in recentyears, have apparently never been attempted. Here, I show that measurements ofthis property of photons have a number of astrophysical applications.Comment: 17 pages plus two figure
