Dark Energy Survey

From SLAC, Jan. 13, 2020: Matching up maps of matter and light from the Dark Energy Survey, hosted at Fermilab, and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.

Enormous scientific collaborations are made up of hundreds upon thousands of individuals, each with their own story. Online collections of profiles, such as Faces of DUNE, the Dark Energy Survey’s Scientist of the Week blog and Humans of LIGO, reveal the sometimes-ignored human sides of scientists.

From DOE, Nov. 20, 2019: Fermilab scientist Antonella Palmese is quoted in this article on scientists’ efforts to get to the bottom of the nature of dark energy. These efforts include the Dark Energy Survey, hosted by Fermilab, and the Dark Energy Spectroscopic Instrument, on which Fermilab scientists are collaborators.

From Inside HPC, Sept. 15, 2019: Argonne and the National Center for Supercomputing Applications use deep learning to analyze Dark Energy Survey data.

The Dark Energy Survey has delivered dark energy constraints combining information from four of its primary cosmological probes for the first time, an approach that may help design other experiments into cosmic acceleration.

For over two decades, Spanish institutions have been collaborating with Fermilab. From the Tevatron era to the lab’s current neutrino experiments, Spain has made important contributions.

From Cosmos, May 6, 2019: An extensive analysis of four different phenomena within the universe points the way to understanding the nature of dark energy, the Dark Energy Survey reveals.

From APS’s Physics, May 1, 2019: The Dark Energy Survey has combined its analysis of four cosmological observables to constrain the properties of dark energy—paving the way for cosmological surveys that will run in the next decade.

The optical lenses for the Dark Energy Spectroscopic Instrument have seen their first light. Fermilab contributed key components to DESI, including the corrector barrel and its support structures, along with vital software that ensures the instrument’s 5,000 robotic positioners are precisely aligned with their celestial targets.

From This Week in Science, Feb. 20, 2019:
This podcast features Antonella Palmese, a postdoctoral research associate at Fermilab and a member of the Dark Energy Survey, which recently completed its six-year observation of a section of the southern sky.
