Rotating perfect fluid bodies in Einstein's general theory of relativity
… perturbation technique, in that a spherically symmetric non-rotating fluid sphere described by Einstein's equations is endowed with rotation, albeit slowly, and the result is expressed and analysed using Taylor's series.<br/><br/>A further consideration is that of the exterior gravitational field, …

Studies of strong-field gravity : testing the black hole hypothesis and investigating spin-curvature coupling
… a candidate black hole is described by the Kerr metric, as predicted by GR for all black holes in vacuum. In the first chapter, we describe how to construct a "bumpy black hole," an object whose spacetime is almost, but not quite, the Kerr metric. We define perturbations to the mass and spin …

Spinning Black Hole Pairs: Dynamics and Gravitational Waves
… The second is defined by geodesics of the Kerr metric and is used exclusively for extreme mass-ratio binaries. In both systems, we define a complete taxonomy for fully three-dimensional orbits. More than just a naming system, the taxonomy provides unambiguous and quantitative descriptions …

TOWARDS PROBING THE STRONG FIELD GRAVITY USING BINARY BLACK-HOLE RINGDOWNS
… waves and settles into a final stable Kerr state. The signal produced during this process is called the ringdown and can be modelled as perturbations on the space-time of the final Kerr black hole. Ringdowns contain information about the strong field dynamics close to the black holes …
