Record-Breaking Run on Frontier Sets New Bar for Simulating the Universe in the Exascale EraResearchers at Argonne National Laboratory used the Frontier supercomputer to run the largest astrophysical simulation of the universe ever conducted. The calculations set a new benchmark for cosmological hydrodynamics simulations and provide a new foundation for simulating the physics of atomic matter and dark matter simultaneously. The simulation size corresponds to surveys undertaken by large telescope observatories, a feat that until now has not been possible at this scale. 

The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has captured the most detailed portrait yet of gases flowing within Cygnus X-3, one of the most studied sources in the X-ray sky.

Alex Bogacz, a senior scientist at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility since 1997, has spent his career in accelerator physics solving problems. From studying complex particle beam dynamics in particle accelerators to designing next-generation machines, his almost four decades of work have recently been recognized by his peers by being named a Fellow of the American Physical Society in October 2024.

The Nation’s first reusable and returnable satellite, Shijian-19,was successfully retrieved and returned to Earth after conducting multiple space experiments in Low Earth Orbit. Among the payloads was an in-orbit material experiment testbed developed by The Hong Kong Polytechnic University (PolyU), which is Hong Kong’s first reusable experimental payload to return from space. The China National Space Administration held the payloads handover ceremony for the Shijian-19 satellite in Beijing last Thursday (24 October), marking the successful completion of the satellite’s return mission.

East Tennessee has become the nerve center for a resurgent nuclear industry. Discover why the region, home to Oak Ridge National Laboratory, is so attractive to this next generation of nuclear businesses.

For the first time, researchers will examine the impact of domestic abuse on families when children of deaf mothers are relied upon to interpret, highlighting the trauma these children may endure as co-victims. 

The latest addition to the computational arsenal of Jefferson Lab is an extraordinary machine with the admittedly ordinary name of “24s.” The 24s cluster at Jefferson Lab will work to unlock the mysteries of the nucleus of the atom. It was funded by the Nuclear and Particle Physics LQCD Computing Initiative of DOE’s Office of Nuclear Physics.
