Random twists of place: How quiet is quantum space-time at the Planck scale?

Fermilab scientist and University of Chicago professor of astronomy and astrophysics Craig Hogan gives perspective on how the Holometer program aims at a tiny scale — the Planck scale — to help answer one of the universe’s most basic questions: Why does everything appear to happen at definite times and places? He contextualizes the results and offers optimism for future researchers.

The perplexing question of missing cosmic antimatter

    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.

    HL-LHC Accelerator Upgrade Project receives approval to move full-speed-ahead from Department of Energy

    The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.

    Four decades and millions of stars later, Sloan Digital Sky Survey co-founder retires

      From The University of Chicago Physical Sciences, Feb. 8, 2021: Fermilab scientist Richard Kron is retiring from the University of Chicago. He co-founded the Sloan Digital Sky Survey, which created the most detailed 3-D maps of the universe and recorded the spectra for more than 3 million astronomical objects. His approach influenced the Dark Energy Survey, which created one of the most accurate dark matter maps of the universe and which Kron will continue to direct.

      The spiral of the Southern Pinwheel

        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.

        Why astronomers are interested in this mysterious signal

          From CNN, Feb. 4, 2021: Fermilab scientist Don Lincoln contextualizes a recent signal that some think may be a sign of extraterrestrial intelligence, explaining the hubbub around the recent a transmission originating from Proxima Centauri. With hope for hearing such a signal one day and pride for humanity’s legacy of looking skyward, Lincoln cautions against reading too much into this transmission, which hasn’t yet been vetted with scientific review.

          UK scientists build core components of global neutrino experiment

          Engineers and technicians in the UK have started production of key piece of equipment for a major international science experiment. The UK government has invested $89 million in the international Deep Underground Neutrino Experiment. As part of the investment, the UK is delivering a series of vital detector components built at the Science and Technology Facilities Council’s Daresbury Laboratory.

          By measuring light from individual stars between galaxy clusters, astronomers find clues about dark matter

            From Universe Today, Feb. 3, 2021: Recent published results from the Dark Energy Survey point to intracluster light — feeble light from rogue stars that don’t belong to a galaxy — as a potential pathway to measure dark matter. Fermilab scientist Yuanyuan Zhang contextualizes the findings.
