LIVERMORE, Calif. -- Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system.

In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state (EOS) of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors...more

October 27, 2011 -Accepted for Publication in the Astrophysical Journal: Astronomers Pin Down Galaxy Collision Rates by Comparing Space Telescope Photographs to Supercomputer Simulations.

The Bolshoi Simulation
A new analysis of images from the Hubble Space Telescope combined with supercomputer simulations of galaxy collisions has cleared up years of confusion about the rate at which smaller galaxies merge to form bigger ones. This paper, led by Jennifer Lotz of Space Telescope Science Institute, is about to be published in The Astrophysical Journal.

September 29, 2011 -Three "Bolshoi" Supercomputer Simulations of the Evolution of the Universe Announced by Authors from University of California, New Mexico State University

The Bolshoi Simulation
Two research articles describing the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made—named “Bolshoi” (the Russian word for “great” or “grand”)—have been accepted for publication in the Astrophysical Journal. The results calculated by the Bolshoi simulation—spectacular visualizations of what the universe was like at time steps 40 million or 80 million years apart—are being made publicly available to the world’s astronomers and astrophysicists...

September 15, 2011 - Published in September 15, 2011 issue of Nature Magazine: Colliding Dwarf Galaxy Triggered Formation of Milky Way's Spiral Arms Revealed by Supercomputer Simulation at University of California, Irvine

  A dwarf galaxy that has collided twice with our own Milky Way galaxy, and that is now coming around once again for a third impact, may well have triggered the formation of the Milky Way’s beautiful spiral arms beginning more than two billion years ago. That is the main conclusion of a paper by Chris W. Purcell and four coauthors published today in the internationally renowned British research journal Nature. Purcell’s findings are based on supercomputer simulations conducted for his Ph.D. dissertation completed in 2010 at the University of California, Irvine, a member of the University of California High-Performance AstroComputing Center (UC-HiPACC).

September 8, 2011 - Los Alamos team aids understanding of astrophysical mystery

Three different stellar jets, captured by the Hubble Space
  September 8, 2011—New Hubble Space Telescope movies of gas jets from stars reveal their fast-changing inner structures. Thanks to the Los Alamos RAGE computer code and a series of supercomputers, a research team now understands more about how observed shock waves, knots, and filamentary structures in these supersonic glowing jets evolve in the stellar environment.
