Massless Particles Orbiting a (2+1) dimensional charged black hole

Abstract

The purpose of this poster is to present orbits of photons around a charged black hole. The black hole considered is a 2+1 dimensional black hole with cosmological constant. The black hole has mass M and charge Q. A thorough analysis of the geometry around the black hole and the horizons will be presented. The effective potential, will also be discussed in relative to the mass and the charge of the black hole.
