Galaxies Fed by Funnels of Fuel

Galaxies Fed by Funnels of Fuel

Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.

The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass.

"Galaxy formation is really chaotic," said Kyle Stewart, lead author of the new study appearing in the May 20th issue of the Astrophysical Journal. "It took us several hundred computer processors, over months of time, to simulate and learn more about how this process works." Stewart, who is now at the California Baptist University in Riverside, Calif., completed the majority of this work while at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Cosmic Swirly Straws Feed Galaxy

Created with the help of supercomputers, this simulation shows the formation of a massive galaxy during the first 2 billion years of the universe. Hydrogen gas is gray, young stars appear blue, and older stars are red. The simulation reveals that gas flows into galaxies along filaments akin to cosmic bendy, or swirly, straws.

Jillian Bellovary of Vanderbilt University, Nashville, Tenn.; Fabio Governato of the University of Washington, Seattle, and the University of Washington's N-Body Shop helped create the simulation. The work was conducted in part using the resources of the Advanced Computing Center for Research and Education at Vanderbilt University.
