Ultimate fate of apparent horizons during a binary black hole merger II: Horizons weaving back and forth in time
Daniel Pook-Kolb, Ivan Booth, Robie A. Hennigar
In this second part of a two-part paper, we discuss numerical simulations of a head-on merger of two non-spinning black holes. We resolve the fate of the original two apparent hori…
Ultimate fate of apparent horizons during a binary black hole merger I: Locating and understanding axisymmetric marginally outer trapped surfaces
Ivan Booth, Robie A. Hennigar, Daniel Pook-Kolb
In classical numerical relativity, marginally outer trapped surfaces (MOTSs) are the main tool to locate and characterize black holes. For five decades it has been known that durin…
Horizons in a binary black hole merger II: Fluxes, multipole moments and stability
Daniel Pook-Kolb, Ofek Birnholtz, Jose Luis Jaramillo +2
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 b…
Horizons in a binary black hole merger I: Geometry and area increase
Daniel Pook-Kolb, Ofek Birnholtz, Jose Luis Jaramillo +2
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 du…
Self-intersecting marginally outer trapped surfaces
Daniel Pook-Kolb, Ofek Birnholtz, Badri Krishnan +1
We have shown previously that a merger of marginally outer trapped surfaces (MOTSs) occurs in a binary black hole merger and that there is a continuous sequence of MOTSs which conn…
The interior of a binary black hole merger
Daniel Pook-Kolb, Ofek Birnholtz, Badri Krishnan +1
We find strong numerical evidence for a new phenomenon in a binary black hole spacetime, namely the merger of marginally outer trapped surfaces (MOTSs). By simulating the head-on c…
