DES

Just because matter is visible doesn’t mean it’s easy to see.

From Physics, Jan. 31, 2023: Fermilab scientists are part of a group of researchers using cross-correlation measurements combining data from the Dark Energy Survey and the South Pole Telescope to determine cosmological parameters with greater precision. The analysis involved more than 150 researchers with results published as a set of three articles in Physical Review D.

Their analysis combines Dark Energy Survey, South Pole Telescope data to better understand the evolution of universe.

From CNET, November 13, 2022: View new photos of radiant galaxies released by NASA using the Dark Energy Camera, developed and tested by Fermilab, and the Hubble Space Telescope. These new images show galaxies scattered across the universe some 200 million light-years away.

The powerful camera built for the Dark Energy Survey has taken more than 1 million photos from its perch in Chile. Here are some of the best.

From Phys.org, September 23, 2021: The Dark Energy Camera, developed and tested at Fermilab, captured images of the
the Fornax Cluster which is about 60 million light-years from Earth. It sits large in the night sky, stretching across more than 100 times larger than the full moon.

From Phys.org, August 24, 2021: Using the powerful 570-megapixel Dark Energy Camera (DECam) created and tested by Fermilab for the DES, astronomers have discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System.

From NOIR Lab, June 25, 2021: The DECam designed, built and tested by Fermilab and funded by DOE, collected the data that lead to the discovery of a giant comet discovered by two astronomers from the University of Pennsylvania.

From NSF’s NOIRLab, June 8, 2021: The Dark Energy Camera (DECam) built and tested by Fermilab, one of the most powerful digital cameras in the world, has taken its one-millionth exposure. DECam’s million exposures include science observations as well as test and calibration exposures taken by the camera while it was being fine-tuned after its construction and installation on the Blanco telescope in 2012.

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.
