Inspiralling, Non-Precessing, Spinning Black Hole Binary Spacetime via Asymptotic Matching
Brennan Ireland, Bruno C. Mundim, Hiroyuki Nakano +1
We construct a new global, fully analytic, approximate spacetime which accurately describes the dynamics of non-precessing, spinning black hole binaries during the inspiral phase o…
Gravitational waves from dark matter collapse in a star
Yasunari Kurita, Hiroyuki Nakano
We investigate the collapse of clusters of weakly interacting massive particles (WIMPs) in the core of a Sun-like star and the possible formation of mini-black holes and the emissi…
Black hole-neutron star binary merger: Dependence on black hole spin orientation and equations of state
Kyohei Kawaguchi, Koutarou Kyutoku, Hiroyuki Nakano +3
We systematically performed numerical-relativity simulations for black hole (BH) - neutron star (NS) binary mergers with a variety of the BH spin orientation and equations of state…
Spin flips in generic black hole binaries
Carlos O. Lousto, James Healy, Hiroyuki Nakano
We study the spin dynamics of individual black holes in a binary system. In particular we focus on the polar precession of spins and the possibility of a complete flip of spins wit…
Possible golden events for ringdown gravitational waves
Hiroyuki Nakano, Takahiro Tanaka, Takashi Nakamura
There is a forbidden region in the parameter space of quasinormal modes of black holes in general relativity. Using both inspiral and ringdown phases of gravitational waves from bi…
Inspiraling black-hole binary spacetimes: Challenges in transitioning from analytical to numerical techniques
Yosef Zlochower, Hiroyuki Nakano, Bruno C. Mundim +3
We explore how a recently developed analytical black-hole binary spacetime can be extended using numerical simulations to go beyond the slow-inspiral phase. The analytic spacetime…
