Three-Dimensional Moving-Mesh Simulations of Galactic Center Cloud G2

Understand

Using three-dimensional, moving-mesh simulations, we investigate the future evolution of the recently discovered gas cloud G2 traveling through the galactic center.

• We consider the case of a spherical cloud initially in pressure equilibrium with the background.
• Our suite of simulations explores the following parameters: the equation of state, radial profiles of the background gas, and start times for the evolution.
• Our primary focus is on how the fate of this cloud will affect the future activity of Sgr A*.
