An Analysis of the Large Scale N-body Simulation using the Minkowski Functionals
Takamichi Nakagami, Takahiko Matsubara, Jens Schmalzing +1
We analyze the Minkowski functionals with a large -body simulation of a standard CDM model, focusing on transition scales between linear and non-linear gravitational evolutio…

Cosmological Redshift-Space Distortion II: distance in an inhomogeneous universe and evolution of bias
Yasushi Suto, Takahiko Matsubara
We discuss the two potentially important effects which should be taken into account in the analysis of the cosmological redshift-space distortion especially at high redshifts; the…
