Reconstructing the whole 6D properties of the Sagittarius stream with
  N-body simulation
  Many modeling of the Sagittarius (Sgr) stream have been attempted, but they
still have difficulties to reproduce its full 6D space-phase properties. Using
N-body simulation with a Milky Way mass of 5.2$\times10^{11}$ M$_{\odot}$ and a
Sgr mass of 9.3$\times10^{8}$ M$_{\odot}$, we have been able to reproduce well
all 3D spatial features of Sgr stream, including its core, leading and trailing
arms, and their associated bifurcations. Moreover, all reported 3D kinematics
properties of the Sgr stream have been qualitatively reproduced without the
need for a massive LMC, although the latter can not be ruled out from this
work. Moreover, we also find that our model fails in reproducing the exact
behaviors of the stream arms in the energy-angular momentum plane. It let us to
suggest that significant further progress can be only achievable after
introducing a major component in the Sgr progenitor, which is the gas that
dominates all Irregular dwarf galaxies in the Sgr mass range.
