The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time 鈥� and the standard model of how the universe works may need an update.
A new data release from the Dark Energy Spectroscopic Instrument is now available for researchers to explore. The collection contains information on 18.7 million galaxies, quasars, and stars 鈥� the largest dataset of its kind ever shared.
Simulations of quantum many-body problems are a challenge for even the most powerful conventional computers. Quantum computing has the potential to solve this challenge using an approach called an analog quantum simulation. To succeed, these simulations need theoretical approximations of how quantum computers represent many-body systems. In this research, nuclear physicists developed a new framework to analyze these approximations and minimize their effects.
Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks鈥攖he tiny particles within鈥攔espond when hit by high-energy photons. The international team includes experts from the University of Adelaide who are exploring the structure of sub-atomic matter to try and provide further insight into the forces that underpin the natural world.
Los Alamos National Laboratory partners with OpenAI to advance national security
Today, the U.S. Department of Energy (DOE) announced it is accepting applications for the 2025 DOE Office of Science Early Career Research Program to support the research of outstanding scientists early in their careers. The program will support over 80 early career researchers for five years at U.S. academic institutions, DOE national laboratories, and Office of Science user facilities.
Today, the U.S. Department of Energy (DOE) announced $71 million in funding for 25 projects in high energy physics that will use the emerging technologies of quantum information science to answer fundamental questions about the universe.
Researchers have analyzed polarized light data from the South Pole Telescope, revealing insights into the early universe. Their findings refine models of cosmic evolution and address the 鈥淗ubble tension鈥� in cosmology.
Even matter ejected by black holes can run into objects in the dark. Using NASA鈥檚 Chandra X-ray Observatory, astronomers have found an unusual mark from a giant black hole鈥檚 powerful jet striking an unidentified object in its path.
Case Western Reserve University President Eric W. Kaler and Provost Joy K. Ward announced that David Gerdes, a renowned physics scholar and department chair from University of Michigan, will become dean of the College of Arts and Sciences on March 1. Gerdes, the Arthur F. Thurnau Professor of Physics and a professor of astronomy, has served on the University of Michigan faculty since 1998 and as chair of the physics department since 2019.
Banks of computer screens stacked two and three high line the walls. The screens are covered with numbers and graphs that are unintelligible to an untrained eye. But they tell a story to the operators staffing the particle accelerator control room. The numbers describe how the accelerator is speeding up tiny particles to smash into targets or other particles.
Nuclear physics theorists have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. The calculations also help validate a method that will be used to make predictions for and analyze data from high-energy experiments at the future Electron-Ion Collider (EIC) at Brookhaven National Laboratory.
Join us for an in-depth presentation by Professor Hesheng Chen from the Institute of High Energy Physics, Chinese Academy of Sciences, as he discusses the exciting developments of the Southern Advanced Photon Source (SAPS).
Argonne scientists are contributing to the success of the Legacy Survey of Space and Time through advanced simulation, analysis and collaborative partnership.
Researchers have developed a way to consistently produce 17-4 PH stainless steel using additive manufacturing, or 3D printing. The rapid change in temperatures that occur in these materials after they are heated by the lasers in 3D printers make it difficult to achieve the toughness needed for 17-4 PH steel. This research used bright X-ray beams to observe those fast changes in real time, then altered the chemical composition to compensate for them.
A research team led by the Department of Energy鈥檚 Oak Ridge National Laboratory has devised a unique method to observe changes in materials at the atomic level. The technique opens new avenues for understanding and developing advanced materials for quantum computing and electronics.
Argonne recently hosted the 25th International Workshop on Neutrinos from Accelerators (NuFact). The workshop brought together leading experts in neutrino physics to share expertise, review progress of experiments and shape future research directions.
The Scientific Data and Computing Center (SDCC) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory now stores more than 300 petabytes of data. That's far more data than would be needed to store everything written by humankind since the dawn of history 鈥� or, if you prefer your media in video format, all the movies ever created.
New method for cathode preparation prevents the particle cracking that caused performance decline with cycling of sodium-ion batteries, which offer a cheaper, more abundant alternative to lithium-ion batteries.
PPPL research scientist Lan Gao received a $2.75 million Early Career Research Program Award from the U.S. Department of Energy for her research on innovative X-ray diagnostics to develop fusion energy. Gao recently became head of PPPL鈥檚 High Energy Density Laboratory Plasmas Division of the Discovery Plasma Science Department.
