Comparison of Post-Newtonian and Numerical Evolutions of Black-Hole Binaries
Hiroyuki Nakano, Manuela Campanelli, Carlos O. Lousto +1
In this paper, we compare the waveforms from the post-Newtonian (PN) approach with the numerical simulations of generic black-hole binaries which have mass ratio , arbitr…
Perturbations of Spacetime around a Stationary Rotating Cosmic String
Kouji Ogawa, Hideki Ishihara, Hiroshi Kozaki +1
We consider the metric perturbations around a stationary rotating Nambu-Goto string in Minkowski spacetime. By solving the linearized Einstein equations, we study the effects of az…
Comparison of Numerical and Post-Newtonian Waveforms for Generic Precessing Black-Hole Binaries
Manuela Campanelli, Carlos O. Lousto, Hiroyuki Nakano +1
We compare waveforms and orbital dynamics from the first long-term, fully non-linear, numerical simulations of a generic black-hole binary configuration with post-Newtonian predict…
Regular second order perturbations of binary black holes: The extreme mass ratio regime
Carlos O. Lousto, Hiroyuki Nakano
In order to derive the precise gravitational waveforms for extreme mass ratio inspirals (EMRI), we develop a formulation for the second order metric perturbations produced by a poi…
Stationary Rotating Strings as Relativistic Particle Mechanics
Kouji Ogawa, Hideki Ishihara, Hiroshi Kozaki +2
Stationary rotating strings can be viewed as geodesic motions in appropriate metrics on a two-dimensional space. We obtain all solutions describing stationary rotating strings in f…
Second and higher-order quasi-normal modes in binary black hole mergers
Kunihito Ioka, Hiroyuki Nakano
Black hole (BH) oscillations known as quasi-normal modes (QNMs) are one of the most important gravitational wave (GW) sources. We propose that higher perturbative order of QNMs, ge…
