Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is the future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the detection of primordial gravitational waves, which could be produced during the inflat

INO: Interplanetary Network of Optical Lattice Clocks

Autor: Ebisuzaki, Toshikazu, Katori, Hidetoshi, Makino, Jun'ichiro, Noda, Atsushi, Shinkai, Hisaaki, Tamagawa, Toru

The new technique of measuring frequency by optical lattice clocks now approaches to the relative precision of $(\Delta f/f)=O(10^{-18})$. We propose to place such precise clocks in space and to use Doppler tracking method for detecting low-frequency

A trick for passing degenerate points in Ashtekar formulation

Autor: Yoneda, Gen, Shinkai, Hisaaki, Nakamichi, Akika

Publikováno v: Phys.Rev. D56 (1997) 2086-2093

We examine one of the advantages of Ashtekar's formulation of general relativity: a tractability of degenerate points from the point of view of following the dynamics of classical spacetime. Assuming that all dynamical variables are finite, we conclu

Event Rates of Gravitational Waves from merging Intermediate mass Black Holes: based on a Runaway Path to a SMBH

Autor: Shinkai Hisaaki

Publikováno v: EPJ Web of Conferences, Vol 168, p 05002 (2018)

Based on a dynamical formation model of a supermassive black hole (SMBH), we estimate the expected observational profile of gravitational wave at ground-based detectors, such as KAGRA or advanced LIGO/VIRGO. Noting that the second generation of detec
