A physicist making great advances in particle detector technology, Estrada is recognized by the American Physical Society Division of Particles and Fields for his creation and development of novel applications for CCD technology that probe wide-ranging areas of particle physics, including cosmology, dark matter searches, neutrino detection and quantum imaging.
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 Forbes, Dec. 27, 2020: Astronomers have long known that the matter that they’ve seen is less than half of the atomic matter that exists. Several hypotheses have been advanced as to where that matter could be found. Fermilab scientist Don Lincoln describes how a team of astronomers has combined a series of astronomical facilities, including the Dark Energy Camera, to look for a filament of gas connecting two galaxy clusters. They were able to image the largest and hottest filament recorded to date.
From UChicago News, Feb. 6, 2020: Fermilab and University of Chicago scientist Brad Benson and colleagues use a different method to calculate the masses of distant galaxies: the polarization, or orientation, of the light left over from the moments after the Big Bang. In doing so, they demonstrate how to “weigh” galaxy clusters using light from the earliest moments of the universe — a new method that could help shed light on dark matter, dark energy and other mysteries of the cosmos.
From Listverse, May 3, 2019: The Dark Energy Camera made this list of 10 brilliant feats of scientific technology, along with LIGO, the Pierre Auger Observatory and the Large Hadron Collider.
From WDCB’s First Light, Jan. 20, 2019: This WDCB interview features Fermilab scientists Brenna Flaugher and Tom Diehl talking about the final nights of the Dark Energy Survey.
After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey will finish taking data on Jan. 9. DES scientists recorded data from more than 300 million distant galaxies. More than 400 scientists from over 25 institutions around the world have been involved in the project, hosted by Fermilab. The collaboration has already produced about 200 academic papers, with more to come.
