Future Shines Bright for Space Science Intern Zachary Raha

Zachary Raha was the kind of kid who always had a side project. Today, Raha—who recently completed a Science Undergraduate Laboratory Internship (SULI) with Nobel laureate Saul Perlmutter of the Physics Division—keeps himself busy with maps of a different scale: the expansion history of the universe as illustrated by Type Ia supernovae.

Rare Supernova Discovery Ushers in New Era for Cosmology

Using an automated supernova-hunting pipeline based at NERSC, astronomers have captured multiple images of a gravitationally lensed Type Ia supernova. This detection is currently the only one of its kind, but astronomers believe that if they can find more, they may be able to measure the rate of the universe’s expansion within 4 percent accuracy. Two Berkeley Lab researchers have a method for identifying more of these events using existing wide-field surveys.

New Measurements Suggest ‘Antineutrino Anomaly’ Fueled by Modeling Error

Results from a new study involving Berkeley Lab scientists could explain a mismatch between predictions and recent measurements of ghostly particles streaming from nuclear reactors—the so-called “reactor antineutrino anomaly” that has puzzled physicists since 2011.

New Study Maps Space Dust in 3-D

A new Berkeley Lab-led study provides 3-D views of space dust in the Milky Way, which could help us understand the properties of this dust and how it affects views of distant objects.

Attention Earthlings: Help Wanted in Finding a New Planet

Data research for a Berkeley Lab-led dark energy experiment benefits citizen science project that seeks the public’s help in the hunt for a hypothesized Neptune-like Planet Nine.

Simulations Show Swirling Rings, Whirlpool-Like Structure in Subatomic ‘Soup’

Powerful supercomputer simulations of high-energy collisions between atomic cores provide new insights about the complex structure of a superhot fluid called the quark-gluon plasma.

Planetarium Show Brings ‘Phantom’ Matter to Life

A new planetarium show, produced in part by Berkeley Lab’s Michael Barnett, is designed to immerse audiences in the search for dark matter, which we have so far detected only through its gravitational effects.

Construction of World’s Most Sensitive Dark Matter Detector Moves Forward

LUX-ZEPLIN, an ultrasensitive dark matter detector, has cleared a major approval milestone and is on track to begin its mile-deep hunt for theoretical particles known as WIMPs in 2020.

Ed Lofgren, Pioneering ‘Rad Lab,’ Berkeley Lab, and Manhattan Project Physicist, dies at 102

Edward Joseph Lofgren, a pioneering Berkeley Lab physicist who was a close associate of E.O. Lawrence and worked on the Manhattan Project, died Sept. 6 at age 102.

Accelerator Operator Stitches Together Storied Career at Bevatron, Cyclotron

Catherine “Reba” Siero, an accelerator operator at Berkeley Lab, has worked for more than two decades at its 88-Inch Cyclotron and earlier worked in particle-beam-based cancer treatments and biology research at the lab.
