Hunting for Dark Matter’s ‘Hidden Valley’

Kathryn Zurek realized a decade ago we may be searching in the wrong places for clues to the unsolved mystery of dark matter. Despite making up 85 percent of the total mass of the universe, we haven’t yet figured out what it’s made of. Now, thanks to extraordinary improvements in experimental sensitivity, “we increasingly know where not to look,” she says. More>

Berkeley Lab Hosts DESI CD-3 Project Review

An international panel of scientists, experts, and observers gathered May 17-19 at Berkeley Lab to participate in a major DOE review of the Dark Energy Spectroscopic Instrument (DESI), a Lab-led project designed to probe the mysteries of dark energy by measuring the distance to galaxies and quasars, and to create a 3-D map of the universe.

In Memoriam: Retired Physicist Jeremy Lys (1938-2016)

Lys passed away earlier this month from complications of Parkinson’s Disease. In 1993 he began particle physics research at Berkeley Lab, joining the group working on the CDF experiment at Fermilab. Later he contributed to the preparation of the ATLAS experiment at the Large Hadron Collider. He left the Lab in 2013. More>

Galtieri Adds Bay to Breakers to Her Impressive Fitness Accomplishments

Last year, Lina Galtieri of the Physics Division ran the Bay to Breakers for the first time. Not such big news, except she retired from the Lab 10 years ago after a 44-year career here as a pioneering female scientist. She came in fourth in her age group. She ran it again this year and came in eighth out of 19 in her age group. The Italian native has also climbed to Mount Everest’s base camp. More>

$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. More>

A Debate Over the Shape of the Invisible Universe

The notion that dark matter might be complex has gained traction in recent years. The field started opening up around 2008, when an experiment called PAMELA detected an excess of positrons over electrons coming from space, which fueled interest in “asymmetric dark matter,” a now-popular model proposed by Berkeley Lab’s Kathryn Zurek and collaborators.
