In this comparison of actual observations with simulations, the top images show Hubble observations of the density of gas in the central portion of two galaxies. The bottom images are computer simulations that are remarkably similar to the Hubble observations. Knots of star formation in the two galaxies show how gas falling into a galaxy's center is controlled by jets from the central black hole.
