### What Happens to Apparent Horizons in a Binary Black Hole Merger?

- PhysicsPhysical review letters
- 2021

The fate of the two original apparent horizons are resolved during the head-on merger of two nonspinning black holes and it is shown that, following the appearance of the outer common horizon and subsequent interpenetration, they continue to exist for a finite period of time before they are individually annihilated by unstable marginally outer trapped surfaces (MOTSs).

Strong numerical evidence is found for a new phenomenon in a binary black hole spacetime, namely, the merger of marginally outer trapped surfaces (MOTSs), and a possibility of proving the Penrose inequality mathematically for generic astrophysical binary back hole configurations is suggested.
