Untangling the Entangled

Researchers used quantum simulations to obtain new insights into the nature of neutrinos — the mysterious subatomic particles that abound throughout the universe — and their role in the deaths of massive stars. The study relied on support from the Quantum Computing User Program, or QCUP, and the Quantum Science Center, a national Quantum Information…

Reaching a New Summit for Supernova Simulations

As a result of largescale 3D supernova simulations conducted on the Oak Ridge Leadership Computing Facility’s Summit supercomputer by researchers from the University of Tennessee and Oak Ridge National Laboratory, astrophysicists now have the most complete picture yet of what gravitational waves from exploding stars look like. This is critical…

Unraveling the “Big Boom”

Simulations performed on Oak Ridge National Laboratory’s Summit supercomputer provide a more detailed look at how stars die and could help unlock new insights into the origins of Earth’s heavy elements. The study, conducted by scientists at ORNL and the University of Tennessee, Knoxville, modeled the collapse and explosion of…

Galactic Winds Demystified

Using the Titan supercomputer at the US Department of Energy’s Oak Ridge National Laboratory, a team of astrophysicists created a set of galactic wind simulations of the highest resolution ever performed. The simulations will allow researchers to gather and interpret more accurate, detailed data that explains how galactic winds affect…

Modeling the Origin Story of the Elements

Written by: Sean M. Simoneau, [email protected], 865.241.0709 More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright “guest star” in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times scattered across the universe. Today, with more…
