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.
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.
It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.
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.
Four Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have been elected into the National Academy of Sciences (NAS) in recognition of their exemplary past and and continuing original research.
In this video, Dark Energy Spectroscopic Instrument (DESI) project participants share their insight and excitement about the project and its potential for new and unexpected discoveries.
On April 1 the dome of the Mayall Telescope near Tucson, Arizona, opened to the night sky, and starlight poured through the assembly of six large lenses that were carefully packaged and aligned for the Dark Energy Spectroscopic Instrument project, which is expected to provide the most precise measurement of the expansion of the universe, and new insight into dark energy.
To help solve a big data program for a new telescope that will conduct a major sky survey of the from the high desert of Chile, a scientific collaboration launched a competition to find the best way to train computers to identify the many types of objects it will be imaging.
New simulations led by researchers working at the Berkeley Lab and UC Berkeley combine decades-old theories to provide new insight about the driving mechanisms in plasma jets that allow them to steal energy from black holes’ powerful gravitational fields and propel it far from their gaping mouths.
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.
