Proposal for Determining the Total Masses of Eccentric Binaries Using Signature of Periastron Advance in Gravitational Waves
Naoki Seto
We propose a new method for determining total masses of low frequency eccentric binaries (such as, neutron star binaries with orbital frequency $f\gsim 10^{-3}$Hz) from their gravi…
Possibility of Direct Measurement of the Acceleration of the Universe Using 0.1 Hz Band Laser Interferometer Gravitational Wave Antenna in Space
Naoki Seto, Seiji Kawamura, Takashi Nakamura
It may be possible to construct a laser interferometer gravitational wave antenna in space with at in this century. We show possible spe…
Numerical Analyses of Weakly Nonlinear Velocity-Density Coupling
Naoki Seto, Naoshi Sugiyama
We study evolution of various statistical quantities of smoothed cosmic density and velocity fields using N-body simulations. The parameter character…
Evolution of Power Spectrum in Non-Gaussian Models
Naoki Seto
Evolution of power spectrum is studied for non-Gaussian models of structure formation. We generalize the dark-matter-approach to these models and find that the evolved spectrum at…
