Two University of Arizona scientists are part of an astrophysics consortium awarded nearly $10 million over the next five years, part of a Department of Energy advanced computing grant to further understanding of supernovae and gamma ray bursts.

In a paper explaining the Computational Astrophysics Consortium's seven-stage project, principal investigator Stan Woosley of the University of California at Santa Cruz said its results could influence future experiments to understand the nature of dark energy, which he called "the greatest mystery in high-energy physics and astronomy today."

Adam S. Burrows, a professor of physics and astronomy, is the UA's principal investigator in the consortium. The other UA scientist in the consortium is Ivan Hubeny, a senior research scientist and astronomy lecturer. Both are members of the Astronomy Department at the Steward Observatory.

Burrows compared the massive nature of the mathematical modeling that will be done to try to understand apparent connections between supernovae and gamma ray bursts to global weather modeling.

"We hope to have a fundamental understanding of the supernova explosions, from the death of the stars that give them birth to their products … the source of most of the heavy elements in nature," said Burrows.

Burrows said the Department of Energy's Scientific Discovery through Advanced Computing grant, the consortium's second SciDAC grant, was a rarity.

He said 240 grant applications were submitted and 30 grants awarded, only one of which was for astrophysics.

Burrows said the announcement of the distribution of the $1.9 million-a-year grant among the participating consortium members would be made in a few weeks.

Other participating institutions in the consortium include Johns Hopkins University, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, Stanford University and the University of California at Berkeley.
