VIDEO: The Making of the Largest 3D Map of the Universe

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.

Dark Energy Instrument’s Lenses See the Night Sky for the First Time

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.

Setting a ‘Gold Standard’ for Ultrasensitive Particle Detectors

Alan “Al” Smith was a pioneer in the “low-background counting” performance of particle detectors – their ability to see ever-fainter signatures of particle interactions. He developed the gold standard for measuring trace levels of radioactivity in materials and components.

Berkeley Lab Researcher Wins Machine-Learning Competition With Code That Sorts Through Simulated Telescope Data

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.

Massive New Dark Matter Detector Gets Its ‘Eyes’

The LUX-ZEPLIN dark matter detector, which will soon begin its deep-underground search for particles thought to account for most matter in the universe, now has “eyes.”

Topping Off a Telescope with New Tools to Explore Dark Energy

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.

Award Finalists Demonstrate Improved Nuclear Physics Code for Supercomputing

André Walker-Loud, a staff scientist at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), is co-leader of a team that is among the six finalists for the Association of Computing Machinery’s Gordon Bell Prize that will be awarded this month.

VIDEO: 5,000 Robots Merge to Map the Universe in 3D

How do you create the largest 3D map of the universe? It’s as easy as teaching 5,000 robots how to “dance.” DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by automatically swiveling fiber-optic positioners (the robots) to point at them and gather their light. In creating this detailed map, scientists hope to learn more about dark energy, which is driving the accelerating expansion of the universe.

A Quantum Leap Toward Expanding the Search for Dark Matter

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.

Berkeley Lab to Push Quantum Information Frontiers With New Programs in Computing, Physics, Materials, and Chemistry

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.
