Confronting the damping of the baryon acoustic oscillations with observation
Hidenori Nomura, Kazuhiro Yamamoto, Gert Huetsi +1
We investigate the damping of the baryon acoustic oscillations in the matter power spectrum due to the quasinonlinear clustering and redshift-space distortions by confronting the m…
Simulations of Baryon Acoustic Oscillations II: Covariance matrix of the matter power spectrum
Ryuichi Takahashi, Naoki Yoshida, Masahiro Takada +7
We use 5000 cosmological N-body simulations of 1(Gpc/h)^3 box for the concordance LCDM model in order to study the sampling variances of nonlinear matter power spectrum. We show th…
Cross-Correlation between UHECR Arrival Distribution and Large-Scale Structure
Hajime Takami, Takahiro Nishimichi, Kazuhiro Yahata +1
We investigate correlation between the arrival directions of ultra-high-energy cosmic rays (UHECRs) and the large-scale structure (LSS) of the Universe by using statistical quantit…
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…
