A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at Berkeley Lab’s Advanced Light Source.
This video and accompanying article highlight the decades of discoveries, achievements and progress in particle accelerator R&D at Berkeley Lab. These accelerators have enabled new explorations of the atomic nucleus; the production and discovery of new elements and isotopes, and of subatomic particles and their properties; created new types of medical imaging and treatments; and provided new insight into the nature of matter and energy, and new methods to advance industry and security, among other wide-ranging applications.
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.
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.
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.
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.
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.
