Negative skewness of radial pairwise velocity in the quasi-nonlinear regime: Zel'dovich approximation
A. Yoshisato, M. Morikawa, H. Mouri
According to N-body numerical simulations, the radial pairwise velocities of galaxies have negative skewness in the quasi-nonlinear regime. To understand its origin, we calculate t…

On the Power Spectrum Density of Gamma Ray Bursts
Motoko Suzuki, Masahiro Morikawa, Izumi Joichi
Gamma ray bursts (GRBs) are known to have short-time variability and power-law behavior with the index -1.67 in the power spectrum density. Reanalyzing the expanded data, we have f…
