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.

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.

From Forbes, Feb. 10, 2021: Fermilab scientist Don Lincoln explains why there should be equal amounts of matter and antimatter in the universe. There aren’t. He discusses several current theories that try to explain the discrepancy. Better understanding this imbalance is an aim of ongoing experiments, such as DUNE, which is being built at Fermilab.

From NOIRLab, Feb. 8, 2021: The Dark Energy Camera, originally used to complete the Dark Energy Survey, has taken the most detailed photo of Messier 83, also known as the Southern Pinwheel galaxy. (In DECam’s second act, scientists can apply for time to use it to collect data that is then made publicly available.) In all, 163 DECam exposures went into creating this image.

From Super Interessante, Jan. 31, 2021: A team of researchers from Fermilab and the National Observatory in Brazil used the light of solitary stars to calculate the mass of some of the largest structures in the cosmos — galaxy clusters. In addition to taking the most detailed measurement ever published of intracluster light, the team’s new method of measurement can help further investigate dark matter.
