Moving mirrors and event horizons in asymptotically non-flat spacetimes

Moving mirrors have been used for a long time as simple models for studying various properties of black hole radiation, such as the thermal spectrum and entanglement entropy. These models are typically constructed to mimic the collapse of a spherically symmetric distribution of matter in the asymptotically Minkowski background. We generalize this correspondence to the case of non-trivial background geometry (e.g. a black hole in the AdS spacetime) and somewhat relax the assumption of spherical symmetry.
