Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal approval milestone prior to startup.
The Sanford Underground Research Facility in South Dakota, which is home to the LUX-ZEPLIN dark matter search project, has begun a transition toward increased operations.
Despite a temporary shutdown of the Dark Energy Spectroscopic Instrument in Arizona – which was in its final stages of testing in preparation to begin mapping millions of galaxies in 3D when the pandemic struck – a variety of project tasks are still moving forward.
A new study by an international team of scientists revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data collected for a U.S. Department of Energy-supported telescope project in Arizona called the Dark Energy Spectroscopic Instrument. The study, published in The Astrophysical Journal, benefited from the winning machine-learning algorithm in an international science competition.
A new study, led by researchers at Berkeley Lab and UC Berkeley, suggests new paths for catching the signals of dark matter particles that have their energy absorbed by atomic nuclei.
A new study by scientists at Berkeley Lab, UC Berkeley, and the University of Michigan – published online this week in the journal Science – concludes that a possible dark matter-related explanation for a mysterious light signature in space is largely ruled out.
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.
In a machine learning challenge dubbed the 2020 Large Hadron Collider Olympics, a team of cosmologists from Berkeley Lab developed a code that best identified a mock signal hidden in simulated particle-collision data.
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.
