From The University of Arizona News, Aug. 1, 2019: The University of Arizona touts two members of the Dark Energy Survey who received DOE awards.
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.
From 365 Days of Astronomy, Feb. 9, 2019: In this podcast, The Dark Energy Survey started in 2013 to map dark energy over 5000 square degrees of sky. Writer and poet Amy Catanzano visited Cerro Tololo Inter-American Observatory during the Dark Energy Survey. In this podcast, Amy discusses her work in quantum poetics, her experience with the Dark Energy Survey and shares some of her poetry.
From Scientific American, Jan. 30, 2019: Fermilab scientist Antonella Palmonese weighs in on a new method of determining the Hubble constant. The method uses data taken from the Fermilab-hosted Dark Energy Survey.
From Nature Reviews Physics, Jan. 28, 2019: The Dark Energy Survey completed its six-year-mission to map more than 300 million distant galaxies; however, an equally arduous task — analyzing the acquired 50 terabytes of data with a view to understanding the expansion of the universe — is just beginning.
