Convergence of post-Newtonian for quasi-circular non-precessing comparable mass ratios BBHs

Dongze Sun, Béatrice Bonga, Leo C. Stein +1

Post-Newtonian (PN) theory provides the analytic foundation for modeling the early inspiral of binary black holes. However, as an asymptotic series, successive PN orders do not nec…

Chaos and fractals of the black hole photon ring

Roman Berens, Peter Galison, Trevor Gravely +2

The photon ring of a Kerr black hole decomposes into a self-similar hierarchy of subrings. Here, we show that this self-similar structure persists in phase space. Moreover, near th…

Parameter matching between horizon quasi-local and point-particle definitions at 1PN for quasi-circular and non spinning BBH systems in harmonic gauge

Dongze Sun, Leo C. Stein

We investigate how commonly used parameter definitions in Post-Newtonian (PN) theory compare with those from Numerical Relativity (NR) for binary black hole (BBH) systems. In NR, m…
