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…
What Happens to Apparent Horizons in a Binary Black Hole Merger?
Daniel Pook-Kolb, Robie A. Hennigar, Ivan Booth
We resolve the fate of the two original apparent horizons during the head-on merger of two non-spinning black holes. We show that following the appearance of the outer common horiz…
