Abstract
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 connects the initial two black holes to the final one. In this paper, we confirm this scenario numerically and we detail further improvements in the numerical methods for locating MOTSs. With these improvements, we confirm the merger scenario and demonstrate the existence of self-intersecting MOTSs formed in the immediate aftermath of the merger. These results will allow us to track physical quantities across the nonlinear merger process and to potentially infer properties of the merger from gravitational wave observations.

N1 - Funding Information: We thank Abhay Ashtekar, Bernd Brugmann, Luis Lehner, and Andrey Shoom for valuable discussions and comments. We are especially grateful to Jose-Luis Jaramillo for extensive discussions and for suggesting the use of bipolar coordinates. The MOTS finder [60] used in this research is developed in Python with SimulationIO [67] being used for reading the numerical simulation data. The libraries SciPy [68], NumPy [69], mpmath [70], SymPy [71] and Matplotlib [72,73] were used for certain numerical, validation and plotting tasks. O.
