Self-Interacting Dark Matter Halos and the Gravothermal Catastrophe
Shmuel Balberg, Stuart L. Shapiro, Shogo Inagaki
We study the evolution of an isolated, spherical halo of self-interacting dark matter (SIDM) in the gravothermal fluid formalism. We show that the thermal relaxation time, , o…
Distribution of Forces in Gravitationally Clustered Systems
Eliani Ardi, Shogo Inagaki
We have studied the distribution of forces in gravitational systems through numerical experiments. Data were taken from an N-body simulation in an expanding universe. Before cluste…
Evolution of Tidally Truncated Globular Clusters with Anisotropy
K. Takahashi, H. M. Lee, S. Inagaki
The evolution of tidally truncated globular clusters is investigated by integrating two-dimensional Fokker-Planck equation that allows the development of velocity anisotropy. We st…
Violent Relaxation of Spherical Stellar Systems
Motokazu Takizawa, Shogo Inagaki
Violent relaxation process of spherical stellar systems is examined by numerical simulations of shell model. The collapse of uniform density sphere both with and without external f…
Energy Principles for Self-Gravitating Barotropic Flows: I. General Theory
Joseph Katz, Shogo Inagaki, Asher Yahalom
The following principle of minimum energy may be a powerful substitute to the dynamical perturbation method, when the latter is hard to apply. Fluid elements of self-gravitating ba…
Energy Principles for Self-Gravitating Barotropic Flows: II. the Stability of Maclaurin Flows
Asher Yahalom Joseph Katz, Shogo Inagaki
We analyze stability conditions of "Maclaurin flows" (self-gravitating, barotropic, two dimensional, stationary streams moving in closed loops around a point) by minimizing their e…
