Radiation Transport in Dynamic Spacetimes
We present early results from a new radiation transport
calculation of gas accretion onto merging binary black holes. We use the
Monte Carlo radiation transport code Pandurata, now generalized for
application to dynamic spacetimes. The time variability of the metric
requires careful numerical techniques for solving the geodesic
equation, particularly with tabulated spacetime data from numerical
relativity codes.
Using a new series of general relativistic magneto-hydrodynamical
simulations of magnetized flow onto binary black holes, we
investigate the possibility for detecting and identifying unique
electromagnetic counterparts to gravitational wave events.
