Horizon news function and quasi-local energy-momentum flux near black hole
arXiv:gr-qc/0703136 · doi:10.1142/9789812834300_0185
Abstract
From the 'quasi-local' definition of horizons, e.g. isolated horizon and dynamical horizon, the consequence quasi-local energy-momentum near horizons can be observed by using the idea of frame alignment. In particular, we find the horizon news function from the asymptotic expansion near horizons and use this to describe the gravitational flux and change of mass of a black hole.
