Non-Gaussianity analysis of GW background made by short-duration burst signals
Naoki Seto
We study an observational method to analyze non-Gaussianity of a gravitational wave (GW) background made by superposition of weak burst signals. The proposed method is based on fou…
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…
Current status of the CLIO project
K Yamamoto, T Uchiyama, S Miyoki +27
CLIO (Cryogenic Laser Interferometer Observatory) is a Japanese gravitational wave detector project. One of the main purposes of CLIO is to demonstrate thermal-noise suppression by…
Resonant speed meter for gravitational wave detection
Atsushi Nishizawa, Seiji Kawamura, Masa-aki Sakagami
Gravitational-wave detectors have been well developed and operated with high sensitivity. However, they still suffer from mirror displacement noise. In this paper, we propose a res…
"Detuned" f(R) gravity and dark energy
Nathalie Deruelle, Misao Sasaki, Yuuiti Sendouda
In gravity theories derived from a f(R) Lagrangian, matter is usually supposed to be minimally coupled to the metric, which hence defines a ``Jordan frame.'' However, since the fie…
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…
