Simulations of Baryon Acoustic Oscillations I: Growth of Large-Scale Density Fluctuations
Ryuichi Takahashi, Naoki Yoshida, Takahiko Matsubara +8
We critically examine how well the evolution of large-scale density perturbations is followed in cosmological -body simulations. We first run a large volume simulation and perfo…

Cosmic Microwave Background--Weak Lensing Correlation: Analytical and Numerical Study of Non-linearity and Implications for Dark Energy
Atsushi J. Nishizawa, Eiichiro Komatsu, Naoki Yoshida +2
Non-linear evolution of density fluctuations yields secondary anisotropies in the cosmic microwave background (CMB), which are correlated with the same density fluctuations that ca…

Lensing Effects on Gravitational Waves in a Clumpy Universe -Effects of Inhomogeneity on the Distance-Redshift Relation-
Chul-Moon Yoo, Ken-ichi Nakao, Hiroshi Kozaki +1
The distance-redshift relation determined by means of gravitational waves in the clumpy universe is simulated numerically by taking into account the effects of gravitational lensin…
