Simulation of Accretion on to Sagittario

Simulations by John F. Hawley, Steven A. Balbus 2002
	Volume rendering of the full simulation (outer radius is at about 100 Schwarzschild radii)
	Volume rendering of the inner region of the simulation
	Cross-section (log density)
Simulations by Daniel Proga 2002
	Larger scales (1000s of Schwarzschild radii)
