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.

AI Finds More Than 1,200 Gravitational Lensing Candidates

A research team with participation by Berkeley Lab physicists has used artificial intelligence to identify more than 1,200 possible gravitational lenses – objects that can be powerful markers for the distribution of dark matter. The count, if all of the candidates turn out to be lenses, would more than double the number of known gravitational lenses.

Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Building a Giant 2D Map of the Universe to Prepare for the Largest 3D Map

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.

Know When to Unfold ’Em: Study Applies Error-Reducing Methods from Particle Physics to Quantum Computing

Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.

A Major Milestone for an Underground Dark Matter Search Experiment

Crews working on the largest U.S. experiment designed to directly detect dark matter completed a major milestone last month, and are now turning their sights toward startup after experiencing some delays due to global pandemic precautions.

VIDEO: Dark Matter Day Q&A with LUX-ZEPLIN Spokesperson Kevin Lesko

Kevin Lesko, a spokesperson for the LUX-ZEPLIN (LZ) dark matter experiment and senior physicist at Berkeley Lab, shares his insights about the mysteries of dark matter, what we know about it, and what we hope to learn about it from LZ, in this Q&A interview at Sanford Lab.

Lab Researcher and Physics Undergrad Shares Poster Project Honoring Black Physicists

Inspired by the nation’s grappling with issues of race and racial discrimination, UC Berkeley physics major and Berkeley Lab student assistant Ana Lyons turned to art as a way to contribute to the conversation.

Natalie Roe Named Berkeley Lab’s Associate Director for Physical Sciences 

Natalie Roe, who joined Lawrence Berkeley National Laboratory (Berkeley Lab) as a postdoctoral fellow in 1989 and has served as Physics Division director since 2012, has been named the Lab’s Associate Laboratory Director (ALD) for the Physical Sciences Area. Her appointment was approved by the University of California today and was effective July 1, 2020. The announcement follows an international search. 

VIDEOS: Science Collaborations Find a Way During COVID-19 Pandemic

Even an underground experiment 4,600 feet below a mountain in Central Italy, and a telescope instrument more than a mile high atop an Arizona mountaintop could not escape the impacts of the COVID-19 pandemic. In these videos, a Berkeley Lab scientist and two Berkeley Lab-affiliated researchers share their experiences of working in international collaborations during the COVID-19 pandemic.
