Bevatron Site Recognized for Historical Contributions to Physics

The site of the former Bevatron, a particle accelerator at Berkeley Lab that operated from 1954 to 1993, has been designated a historic site by the American Physical Society for its exemplary contributions to physics.

Five Berkeley Lab Scientists Receive Prestigious Five-Year Research Grant

Five scientists at Berkeley Lab have been selected by the U.S. Department of Energy’s Office of Science to receive funding through the Early Career Research Program (ECRP).

Nathalie Palanque-Delabrouille to Lead Berkeley Lab’s Physics Division

Nathalie Palanque-Delabrouille, a cosmologist and research director at the Institute for Research on the Fundamental Laws of the Universe at the CEA Paris-Saclay research center, has been selected to serve as the next division director of Lawrence Berkeley National Laboratory’s (Berkeley Lab) Physics Division. Her appointment will be effective in late August. The announcement follows an

Successful Start of Dark Energy Spectroscopic Instrument (DESI) Follows Record-Setting Trial Run

A five-year quest to map the universe and unravel the mysteries of “dark energy” is beginning officially today, May 17, at Kitt Peak National Observatory near Tucson, Arizona.

Detector Technology Developed at Berkeley Lab Yields Unprecedented 3D Images, Heralding Far Larger Application to Study Neutrinos

An experiment to capture unprecedented 3D images of the trajectories of charged particles has been demonstrated using cosmic rays as they strike and travel through a cryostat filled with a ton of liquid argon. The results confirm the capabilities of a novel detector technology for particle physics.

Supernovae Twins Open Up New Possibilities for Precision Cosmology

Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions – one of their tried-and-true tools for studying the mysterious dark energy that is making the universe expand faster and faster.

Berkeley Lab Scientist’s Work Deciphering Early Universe Secrets Garners 2021 Gruber Cosmology Prize

A trio of physicists – including Uroš Seljak of Lawrence Berkeley National Laboratory – has been awarded the 2021 Gruber Cosmology Prize for their work studying the large-scale structure of the universe as well as the properties of its first instant of existence.

Missing Baryons Found in Far-Out Reaches of Galactic Halos

Researchers have channeled the universe’s earliest light – a relic of the universe’s formation known as the cosmic microwave background (CMB) – to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein’s theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.

U.S. Magnet Development Project for CERN Particle Collider Upgrade Moves Forward

The U.S. Department of Energy has formally approved a key milestone in the High-Luminosity LHC Accelerator Upgrade Project being carried out at eight U.S. institutions, including the DOE’s Berkeley Lab.

Researchers Hunt for New Particles in Particle Collider Data

Berkeley Lab researchers participated in a study that used machine learning to scan for new particles in three years of particle-collision data from CERN’s ATLAS detector.
