Seeing the Universe Through New Lenses

A new study by an international team of scientists revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data collected for a U.S. Department of Energy-supported telescope project in Arizona called the Dark Energy Spectroscopic Instrument. The study, published in The Astrophysical Journal, benefited from the winning machine-learning algorithm in an international science competition.

Study: Could Dark Matter Be Hiding in Existing Data?

A new study, led by researchers at Berkeley Lab and UC Berkeley, suggests new paths for catching the signals of dark matter particles that have their energy absorbed by atomic nuclei.

New Technique Looks for Dark Matter Traces in Dark Places

A new study by scientists at Berkeley Lab, UC Berkeley, and the University of Michigan – published online this week in the journal Science – concludes that a possible dark matter-related explanation for a mysterious light signature in space is largely ruled out.

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.

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.

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.

Massive New Dark Matter Detector Gets Its ‘Eyes’

The LUX-ZEPLIN dark matter detector, which will soon begin its deep-underground search for particles thought to account for most matter in the universe, now has “eyes.”

Acrylic Tanks Provide Clear Window Into Dark Matter Detection

Scientists have a new window into the search for dark matter – an acrylic vessel that features a grouping of 12-foot-tall transparent tanks with 1-inch-thick walls. The tanks, which will surround a central detector for a nearly mile-deep experiment under construction in South Dakota called LUX-ZEPLIN (LZ), will be filled with liquid that produces tiny flashes of light in some particle interactions.
