From Kathimerini (Greece), June 14, 2021: A multinational team of 400 researchers from 25 research centers in seven countries announced the results of the DES study that looked at 226 million galaxies and thousands of supernova explosions. The DES measurements, like those of other similar galactic surveys, informed us that the current universe is less dense than our model predicts.
From Yahoo, May 30, 2021: Scientists from the Dark Energy Survey collaboration have just released the best dark matter map yet, but it’s not answering every question — if anything, the cosmos may be more mysterious than ever.
From CNN, June 3, 2021: Fermilab’s Don Lincoln covers the capabilities of the Dark Energy Spectroscopic Instrument, or DESI, in mapping the structure of the entire cosmos.
From Universe Today, May 30, 2021: The Dark Energy Survey camera (DECam) was funded by the Department of Energy (DOE) and was built and tested at Fermilab. The DES took place over 6 years from 2013 to 2019, and looked at over 1/8th of the night sky for a total of 758 night
From The Florida News Times, May 28, 2021: A highly accurate analysis of the DES data from the first three years of the study, show hints from previous DES data and other important experiments in the universe today are a few percent less than expected. The Dark Energy Survey Camera (DECam) used in the survey was specially designed for the Dark Energy Survey, and was funded by the Department of Energy (DOE) and built and tested at DOE’s Fermilab.
The Dark Energy Survey collaboration has created the largest ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of over 7 billion light years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe, the standard cosmological model. Nevertheless, there remain hints from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.
From the University of Chicago, May 21, 2021: Long-time University of Chicago professor of astronomy and astrophysics, Richard Kron created the Sloan Digital Sky Survey which set the stage for the Dark Energy Survey. Although he is retiring this year after 40 years of mapping the universe, he plans on staying on as director of the Dark Energy Survey.
DESI will capture and study the light from tens of millions of galaxies and other distant objects to better understand our universe and the properties of dark energy. The formal start of DESI’s five-year survey follows a four-month trial run of its custom instrumentation that captured 4-million spectra of galaxies — more than the combined output of all previous spectroscopic surveys. Fermilab has contributed multiple components to the international collaboration led by Berkeley Lab.
From Marianne TV (France), April 21, 2021: An interview on the Muon g-2 experiment result with Laurent Lellouch, CNRS research director at the Theoretical Physics Center and the Universe Physics Institute.
From Jumbo News, March 31, 2021: Fermilab’s Josh Frieman, Tom Diehl, Antonella Palmese, and Rich Kron as part of the Dark Energy Survey collaboration, have completed scanning a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies.
