Chasing clues about the infant universe in relic light known as the cosmic microwave background, or CMB, Berkeley Lab scientists are devising more elaborate and ultrasensitive detector arrays to measure the properties of this light with increasing precision.
Key components for the sky-mapping Dark Energy Spectroscopic Instrument, weighing about 12 tons, were hoisted atop the Mayall Telescope at Kitt Peak National Observatory near Tucson, Arizona, and bolted into place last week, marking a major project milestone.
Experiments at Berkeley Lab have helped scientists to zero in on a low-temperature chemical mechanism that may help to explain the complex molecular compounds that make up the nitrogen-rich haze layer surrounding Titan, Saturn’s largest moon.
Through a new research program supported by the U.S. Department of Energy’s Office of High Energy Physics, a consortium of researchers from Berkeley Lab, UC Berkeley, and the University of Massachusetts Amherst will develop sensors that enlist the seemingly weird properties of quantum physics to probe for dark matter particles in new ways, with increased sensitivity, and in uncharted regions.
Lawrence Berkeley National Laboratory (Berkeley Lab) this week announced support from the Department of Energy that significantly expands Berkeley Lab’s research efforts in quantum information science, an area of research that harnesses the phenomenon of quantum coherence, in which two or more particles are so tightly entangled that a change to one simultaneously affects the other. Quantum information science seeks to utilize this phenomenon to hold, transmit, and process information.
A large titanium cryostat designed to keep its contents chilled to minus 148 degrees has completed its journey from Europe to South Dakota, where it will become part of a next-generation dark matter detector for the LUX-ZEPLIN (LZ) experiment.
An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth.
Julian Borrill, who leads the Computational Cosmology Center in Berkeley Lab’s Computational Research Division, has been elected co-spokesperson of CMB-S4, a next-generation ground-based experiment to study the faint relic radiation from the Big Bang.
A new particle detector design proposed at the U.S. Department of Energy’s Berkeley Lab could greatly broaden the search for dark matter – which makes up 85 percent of the total mass of the universe yet we don’t know what it’s made of – into an unexplored realm.
Scientists have used experiments at Berkeley Lab to retrace the chemical steps leading to the creation of complex hydrocarbons in space. They showed pathways to forming 2-D carbon-based nanostructures in a mix of heated gases.
