The N-Body 2PN Hamiltonian and Numerical Integration of the Equations of Motion
Felix M. Heinze, Gerhard Schäfer, Bernd Brügmann
To date, the second-order post-Newtonian (2PN) Hamiltonian has been known in closed analytic form only for systems of up to three point masses. In this paper, we present an analyti…

Exploring the Dynamics of General Relativistic Binary-Single and Binary-Binary Encounters of Black Holes
Felix M. Heinze, Bernd Brügmann, Tim Dietrich +1
In this exploratory study, we demonstrate the capability of the numerical-relativity code BAM to simulate fully relativistic black-hole binary-single and binary-binary encounters.…
