Massless Particle Orbiting around a (3+1) Black Hole

Abstract

The purpose of this poster is to present orbits of photons around a black hole. The black hole considered is a 3+1 dimensional black hole with cosmological constant. The black hole has mass M. A thorough analysis of the geometry around the black hole and the horizons will be presented. The effective potential, and temperature of the black hole also will be discussed in relative to the mass of the black hole.
