A Capture Scenario for Globular Cluster Omega Centauri
Toshio Tsuchiya, Dana I. Dinescu, Vladimir I. Korchagin
We explore an accretion origin for Omega Cen by N-body modeling of the orbital decay and disruption of a Milky-Way dwarf satellite. This work is focused on studying a particular sa…
Constraints of the Clumpyness of Dark Matter Halos Through Heating of the Disk Galaxies
E. Ardi, T. Tsuchiya, A. Burkert
Motivated by the presence of numerous dark matter clumps in the Milky Way's halo as expected from the cold dark matter cosmological model, we conduct numerical simulations to exami…
Contribution of the Large Magellanic Cloud to the Galactic Warp
Toshio Tsuchiya
Multi-scale interaction between the LMC, Galactic halo, and the disk is examined with N-body simulations, and precise amplitudes of the Galactic warp excitation are obtained. The G…
On the Origin of Faint Intracluster Starlight in Coma
Vladimir Korchagin, Toshio Tsuchiya, Shoken M. Miyama
Using N-body numerical simulations, we examine possible mechanisms for the origin of the intracluster starlight features recently discovered in the Coma cluster of galaxies. We sho…
Time evolution of galactic warps in prolate haloes
Makoto Ideta, Shunsuke Hozumi, Toshio Tsuchiya +1
A recent observation with the Hipparcos satellite and some numerical simulations imply that the interaction between an oblate halo and a disc is inappropriate for the persistence o…
Time scales of relaxation and Lyapunov instabilities in a one-dimensional gravitating sheet system
Toshio Tsuchiya, Naoteru Gouda
The relation between relaxation, the time scale of Lyapunov instabilities, and the Kolmogorov-Sinai time in a one-dimensional gravitating sheet system is studied. Both the maximum…
