DESCRIPTION:Stellar streams produced by dissolving globular clusters are h
 ighly sensitive probes of the dark matter content of the Milky Way\, and c
 an sometimes be used to constrain the mass of its satellite galaxies. One 
 of the largest such satellites\, the Sagittarius Dwarf Spheroidal Galaxy (
 Sgr)\, is currently undergoing tidal disruption\, meaning that its initial
  mass was much greater than that of the observed remnant\, possibly > 4 x 
 10^10 M⊙. We consider the effects of such a large mass on the GD-1 stell
 ar stream by running simulations with various initial masses of Sgr. We se
 ek to answer whether these masses are consistent with the level of disrupt
 ion observed in the real stream.
