From Physics World, June 12, 2019: Physics World posts a video recorded inside the ProtoDUNE neutrino detector by the particle physicist and vocalist Anastasia Basharina-Freshville, who sing-explains why the noble gas is used to detect the elusive particles.
Right now could be considered one of the best — and most uncertain — times in theoretical physics. That’s what Symmetry heard in interviews with 10 junior faculty in the field. They talk about what keeps them up at night, their favorite places to think and how they explain their jobs to nonscientists.
From Rapid City Journal, July 12, 2019: Fermilab Director Nigel Lockyer was the guest for a free public speaker series held one day prior to Neutrino Day, a full day of neutrino-themed public activities in Lead. Lockyer spoke about is known as the Deep Underground Neutrino Experiment (DUNE), housed in the Long Baseline Neutrino Facility (LBNF), which will have its South Dakota component at the Sanford Underground Research Facility in the former Homestake mine. It’s a billion-dollar international collaboration, and it’s described as the largest particle physics project ever built in the United States.
A new study shows that light dark matter is 1000 times less likely to bump into regular matter than previous analyses allowed.
From Inside HPC, July 3, 2019: Particle physics researchers are using custom integrated circuits called FPGAs in combination with other computing resources to process massive quantities of data at extremely fast rates to find clues to the origins of the universe. This requires filtering sensor data in real time to identify novel particle substructures that could contain evidence of the existence of dark matter and other physical phenomena. A growing team of physicists and engineers from Fermilab, CERN and other institutions, co-led by Fermilab scientist Nhan Tran, wanted to have a flexible way to optimize custom-event filters in the CMS detector they are working on at CERN.
Few numbers have gotten under astronomers’ skin like the Hubble constant. In fact, experts have debated the value of this single parameter for 90 years, and if astronomers can measure its value with great precision, they’ll be one step closer to solving some of the other grand astronomical mysteries of our age. There’s just one problem: The measurements they’ve taken don’t agree. The discrepancy makes scientists question whether something is amiss in our understanding of the universe.
A lot of people say they would like to travel to Mars, but Zoe Townsend doesn’t just talk the talk. As a mechanical engineer at CERN, she knows the importance of putting ideas to the test. To see if she could actually handle the unique challenges posed by living and doing science on another planet, Townsend spent 12 days on a simulated Mars mission in the deserts of Utah.
From CNN, June 21, 2019: Fermilab scientist Don Lincoln talks about the recent UFO sightings in the news. It’s plausible that what pilots have been seeing is something with an ordinary explanation, whether it be an instrumental glitch or some other unexplained artifact.
Scientists at SLAC National Accelerator Laboratory are building the world’s largest digital camera for astronomy and astrophysics — a minivan-sized 3200-megapixel “eye” of the future Large Synoptic Survey Telescope that will see light in 2022. In the meantime, the lab has completed its work on a miniature version that will soon be used for testing the telescope and taking LSST’s first images of the night sky. ComCam will help test the observatory once it is installed in Chile later this year.
From Science News, June 17, 2019: The particles could be spotted when they slam into electrons or atomic nuclei in the crystals, says Fermilab scientist Noah Kurinsky.
