Building a Giant 2D Map of the Universe to Prepare for the Largest 3D Map

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.

Lab Researcher and Physics Undergrad Shares Poster Project Honoring Black Physicists

Inspired by the nation’s grappling with issues of race and racial discrimination, UC Berkeley physics major and Berkeley Lab student assistant Ana Lyons turned to art as a way to contribute to the conversation.

Natalie Roe Named Berkeley Lab’s Associate Director for Physical Sciences 

Natalie Roe, who joined Lawrence Berkeley National Laboratory (Berkeley Lab) as a postdoctoral fellow in 1989 and has served as Physics Division director since 2012, has been named the Lab’s Associate Laboratory Director (ALD) for the Physical Sciences Area. Her appointment was approved by the University of California today and was effective July 1, 2020. The announcement follows an international search. 

VIDEOS: Science Collaborations Find a Way During COVID-19 Pandemic

Even an underground experiment 4,600 feet below a mountain in Central Italy, and a telescope instrument more than a mile high atop an Arizona mountaintop could not escape the impacts of the COVID-19 pandemic. In these videos, a Berkeley Lab scientist and two Berkeley Lab-affiliated researchers share their experiences of working in international collaborations during the COVID-19 pandemic.

Now Complete, Telescope Instrument is Poised to Begin Its Search for Answers About Dark Energy

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.

DESI Team Prepares for Telescope Instrument’s Restart after Unexpected Shutdown

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.

Seeing the Universe Through New Lenses

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.

Looking Up From the Mountaintop: Q&A With a Telescope Instrument’s Lead Observer

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.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos

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.

3 Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument

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.
