Abstract |
Pulsar timing offers the possibility to test the theory of gravity in the strong field regime. Particularly promising laboratories for such tests are pulsar--black hole binaries. In such a system it is therefore of paramount importance to accurately model the effects of General Relativity. We present an exact analytical calculation for the relativistic propagation delay of the signal of a pulsar orbiting a supermassive black hole. We use this result to test the accuracy of the usually employed post--Newtonian approximation methods. |
