Exploring tidal effects of coalescing binary neutron stars in numerical relativity II: Longterm simulations
Kenta Hotokezaka, Koutarou Kyutoku, Hirotada Okawa +1
We perform new longterm (15-16 orbits) simulations of coalescing binary neutron stars in numerical relativity using an updated Einstein's equation solver, employing low-eccentricit…
Higher dimensional Numerical Relativity: code comparison
Helvi Witek, Hirotada Okawa, Vitor Cardoso +5
The nonlinear behavior of higher dimensional black hole spacetimes is of interest in several contexts, ranging from an understanding of cosmic censorship to black hole production i…
Impact of the second order self-forces on the dephasing of the gravitational waves from quasi-circular extreme mass-ratio inspirals
Soichiro Isoyama, Ryuichi Fujita, Norichika Sago +2
The accurate calculation of long-term phase evolution of gravitational wave (GW) forms from extreme (intermediate) mass ratio inspirals (E(I)MRIs) is an inevitable step to extract…
Is super-Planckian physics visible? -- Scattering of black holes in 5 dimensions
Hirotada Okawa, Ken-ichi Nakao, Masaru Shibata
It may be widely believed that probing short-distance physics is limited by the presence of the Planck energy scale above which scale any information is cloaked behind a horizon. I…
Development of displacement- and frequency-noise-free interferometer in 3-D configuration for gravitational wave detection
K. Kokeyama, S. Sato, A. Nishizawa +3
The displacement- and frequency-noise-free interferometer (DFI) is a multiple laser interferometer array for gravitational wave detection free from both the displacement noise of o…
Search for a stochastic background of 100-MHz gravitational waves with laser interferometers
Tomotada Akutsu, Seiji Kawamura, Atsushi Nishizawa +11
This letter reports the results of a search for a stochastic background of gravitational waves (GW) at 100 MHz by laser interferometry. We have developed a GW detector, which is a…
