Description
We present current X-ray observations and simulations showing how gravitational lensing is used to infer the structure near the event horizons of black holes, constrain the spin of the supermassive black hole and its evolution over cosmic time and test general relativity in the strong-gravity regime.
We also show how these observations can be expanded to a statistically large sample of z = 0.5-5 lensed quasars with the predicted discovery by LSST of > 4,000 additional gravitationally lensed systems and with a next generation X-ray telescope having a spatial resolution of <?0.5arcsec to resolve the lensed images and a collecting area of >? 0.5 m^2 at 1 keV.
