Extreme Gravitational Lensing near Rotating Black Holes
Kris Beckwith, Chris Done
We describe a new approach to calculating photon trajectories and gravitational lensing effects in the strong gravitational field of the Kerr black hole. These techniques are appli…
Observing braneworld black holes
Ruth Gregory, Richard Whisker, Kris Beckwith +1
Spacetime in the vicinity of an event horizon can be probed using observations which explore the dynamics of the accretion disc. Many high energy theories of gravity lead to modifi…
Accurate Modelling of Relativistic Iron Lines from Accretion Discs
Kris Beckwith, Chris Done
Observations of fluorescent iron lines from accreting black holes provide one of the best tests of strong field gravity available to date, and the only current observational tool t…
Iron Line Profiles in Strong Gravity
Kris Beckwith, Chris Done
We describe a new code which can accurately calculate the relativistic effects which distort the emission from an accretion disc around a black hole. We compare our results for a d…
