Researchers are using DOE’s most powerful computing systems, including the nation’s top-ranked machine, ORNL’s Titan, to simulate the evolution of the universe as it expands across billions of years.

Using OLCF resources, scientists have simulated matter at the core’s bounce, when the shock wave starts to develop.

Nuclear physics experts from around the country gathered July 23–24 in Washington, D.C., to discuss the future of computational nuclear physics.

A recent cover of Science magazine features a visualization from a long-standing INCITE/OLCF user team’s quest to discover the mechanism behind the explosions of core-collapse supernovas.

A team of astrophysicists and computational scientists is using the power of the OLCF’s Jaguar to virtually blow up dwarf stars, revealing the secrets of the biggest thermonuclear explosions in the universe.

Homa Karimabadi’s team, in close collaboration with William Daughton at Los Alamos National Laboratory, is currently using the OLCF’s Jaguar supercomputer to better understand the processes giving rise to space weather.

A team led by University of Iowa astrophysicist Gregory Howes is using ORNL’s Jaguar supercomputer to explore astrophysical plasma.

Researchers use Jaguar to simulate ignition in type Ia supernova explosions.
