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…
Optimal Location of Two Laser-interferometric Detectors for Gravitational Wave Backgrounds at 100 MHz
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have been developed and given constraints on the energy density of GWB in a broad range of frequencies. The…
Laser-interferometric Detectors for Gravitational Wave Background at 100 MHz : Detector Design and Sensitivity
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have developed and given direct and indirect constraints on the energy density of GWB in a broad range of f…
A Consistency Relation in Cosmology
Takeshi Chiba, Ryuichi Takahashi
We provide a consistency relation between cosmological observables in general relativity without relying on the equation of state of dark energy. The consistency relation should be…
