In this Q&A Satya Gontcho A Gontcho, a lead observer for the Dark Energy Spectroscopic Instrument, shares her experiences at the DESI site near Tucson, Arizona, including evening observing stints to run through detailed checklists and probe how the instrument’s components are working.
A team led by scientists that included Berkeley Lab researchers has simulated the formation of a disc of matter, a giant burst of ejected matter, and the startup of energetic jets in the aftermath of a merger by two neutron stars.
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.
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.
A new instrument mounted atop a telescope in Arizona has aimed its robotic array of 5,000 fiber-optic “eyes” at the night sky to capture the first images showing its unique view of galaxy light.
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.
