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.

3-D Galaxy-mapping Project Enters Construction Phase

A 3-D sky-mapping project that will measure the light of millions of galaxies and explore the nature of dark energy has received approval to move forward with construction.

Dark Energy Measured with Record-Breaking Map of 1.2 Million Galaxies

A team of hundreds of physicists and astronomers, including those from Berkeley Lab, have announced results from the largest-ever, three-dimensional map of distant galaxies. The team constructed this map to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe.

Researchers Gear Up Galaxy-seeking Robots for a Test Run

A prototype system that will test a planned array of 5,000 robots for a sky-mapping instrument is taking shape at Berkeley Lab. Dubbed ProtoDESI, the scaled-down, 10-robot system will run through a series of tests on a telescope in Arizona from August-September.

Radiation 101: DoseNet Delivers Environmental Data as an Educational Tool

DoseNet, a radiation-monitoring outreach project supported by Berkeley Lab and UC Berkeley, has a broad aim to inform and connect students and communities using science and data.

Hunting for Dark Matter’s ‘Hidden Valley’

Kathryn Zurek realized a decade ago that we may be searching in the wrong places for clues to one of the universe’s greatest unsolved mysteries: dark matter. Despite making up an estimated 85 percent of the total mass of the universe, we haven’t yet figured out what it’s made of.

3 Knowns and 3 Unknowns about Dark Matter

While we can’t see dark matter, we are learning more about it. Here are three knowns and three unknowns about dark matter.

$40M to Establish New Observatory Probing Early Universe

A new astronomy facility, the Simons Observatory, is planned in Chile’s Atacama Desert to boost ongoing studies of the evolution of the universe, from its earliest moments to today. The observatory will probe the subtle properties of the universe’s first light, known as cosmic microwave background radiation.
