Dark Matter Day Q&A with Berkeley Lab Physicist Quentin Riffard

Quentin Riffard, a project scientist for the LUX-ZEPLIN dark matter detection experiment that is now being installed at the Sanford Underground Research Facility in Lead, South Dakota, shares his experiences in researching dark matter in this Q&A.

Dark Matter Experiment’s Central Component Takes a Deep Dive – Nearly a Mile Underground

Last week, crews at the Sanford Underground Research Facility in South Dakota strapped the central component of LUX-ZEPLIN – the largest direct-detection dark matter experiment in the U.S. – below an elevator and s-l-o-w-l-y lowered it 4,850 feet down a shaft formerly used in gold-mining operations.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos

A new instrument mounted atop a telescope in Arizona has aimed its robotic array of 5,000 fiber-optic “eyes” at the night sky to capture the first images showing its unique view of galaxy light.

Q&A with Berkeley Lab Nuclear Scientist Maria Żurek

Maria Żurek, a postdoctoral researcher at Berkeley Lab, was invited to attend the 2019 Lindau Nobel Laureate Meeting in Lindau, Germany, in early July. The annual event offers networking opportunities for students, postdoctoral researchers, and Nobel laureates from around the world. A total of 580 researchers and 39 Nobel laureates from 89 countries attended this year’s meeting.

Two Berkeley Lab Researchers Receive DOE Early Career Research Awards

Two scientists at Lawrence Berkeley National Laboratory have been selected by the U.S. Department of Energy’s Office of Science to receive significant funding for research through its Early Career Research Program.

Some Assembly Required: Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment

Most of the remaining components needed to fully assemble an underground dark matter-search experiment called LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June. When complete, LZ will be the largest, most sensitive U.S.-based experiment yet that is designed to directly detect dark matter particles.

Simons Foundation Contributes $20M More to Observatory Exploring Early Universe

The Simons Observatory, a Berkeley Lab-involved project under construction in Chile’s Atacama Desert that will measure the properties of universe’s early light – the cosmic microwave background (CMB) – with extreme precision, has received a new commitment of $20 million from the Simons Foundation.

What if Dark Matter is Lighter? Report Calls for Small Experiments to Broaden the Hunt

Theorized dark matter particles haven’t yet shown up where scientists had expected them. So Berkeley Lab researchers are now designing new and nimble experiments that can look for dark matter in previously unexplored ranges of particle mass and energy, and using previously untested methods.

A New Filter to Better Map the Dark Universe

To address messy measurements of the cosmic web that connects matter in the universe, researchers at Berkeley Lab developed a way to improve the accuracy and clarity of these measurements based on the stretching of the universe’s oldest light.

The ‘Little’ Computer Cluster That Could

A computer cluster at Berkeley Lab, which switched off last month, since 1996 had served as a steady workhorse in supporting groundbreaking physics research conducted by large collaborations.
