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…
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…
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…
Effective Search Templates for a Primordial Stochastic Gravitational Wave Background
Takeshi Chiba, Yoshiaki Himemoto, Masahide Yamaguchi +1
We calculate the signal-to-noise ratio (SNR) of the stochastic gravitational-wave background in an extreme case that its spectrum has a sharp falloff with its amplitude close to th…
