Tunnelling From Gödel Black Holes

Abstract

We consider the spacetime structure of Kerr-Gödel black holes, analyzing their parameter space Kerr-Gödel in detail. We apply the tunnelling method to compute their temperature and compare the results to previous calculations obtained via other methods. We claim that it is not possible to have the CTC horizon in between the two black hole horizons and include a discussion of issues that occur when the radius of the CTC horizon is smaller than the radius of both black hole horizons.
