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

TLDR
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).

Horizon area bound and MOTS stability in locally rotationally symmetric solutions

In this paper, we study the stability of marginally outer trapped surfaces (MOTS), foliating horizons of the form r = X ( τ ), embedded in locally rotationally symmetric class II perfect fluid

Horizons in a binary black hole merger II: Fluxes, multipole moments and stability

We study in detail the dynamics and stability of marginally trapped surfaces during a binary black hole merger. This is the second in a two-part study. The first part studied the basic geometric

Interior of a Binary Black Hole Merger.

TLDR
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.

Horizon dynamics of distorted rotating black holes

We present numerical simulations of a rotating black hole distorted by a pulse of ingoing gravitational radiation. For strong pulses, we find up to five concentric marginally outer trapped surfaces.

Horizons in a binary black hole merger I: Geometry and area increase

Recent advances in numerical relativity have revealed how marginally trapped surfaces behave when black holes merge. It is now known that interesting topological features emerge during the merger,

We study the open and closed axisymmetric marginally outer trapped surfaces contained in leaves of constant Painleve-Gullstrand time for Schwarzschild spacetimes. We identify a family of closed MOTS

Self-intersecting marginally outer trapped surfaces

TLDR
This paper confirms the merger scenario and demonstrates the existence of self-intersecting MOTSs formed in the immediate aftermath of the merger, and details further improvements in the numerical methods for locating Motss.

We present simulations of binary black-hole mergers in which, after the common outer horizon has formed, the marginally outer trapped surfaces (MOTSs) corresponding to the individual black holes

Inside the final black hole: puncture and trapped surface dynamics

A popular approach in numerical simulations of black hole binaries is to model black holes as punctures in the fabric of spacetime. The location and the properties of the black hole punctures are
