From CNN, Nov. 28, 2020: The explosion of a supernova is so powerful that modern telescopes can see it half a universe away. A cautious person might wonder, “What would happen to Earth if this happened to a nearby star?” In this article, Fermilab scientist Don Lincoln discusses a paper from University of Colorado at Boulder’s Robert Brakenridge, who claims that he has found evidence here on Earth of nearby supernovae. What form does this evidence take? Ancient radioactive tree rings.
The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.
From Futurism, Aug. 19, 2020: When an ambitious new Fermilab-hosted experiment called DUNE begins its work, physicists believe they’ll be able to learn a whole lot more about supernova explosions than ever before. That’s because DUNE is expected to be sensitive to an extremely elusive particle called a neutrino that’s blasted far and wide across the cosmos when a star explodes. According to a new paper shared online on Saturday, physicists expect DUNE to scoop up a never-before-detected kind of neutrino and, in doing so, break down why and how stars die in unprecedented detail.
The international Deep Underground Neutrino Experiment collaboration has published a paper about its capability for performing supernova physics. It details the kind of activity DUNE expects in the detector during a supernova burst, how DUNE will know once a supernova occurs and what physics DUNE will extract from the neutrinos. DUNE’s unique strength is its sensitivity to a particular type of neutrino called the electron neutrino, which will provide scientists with supernova data not available from any other experiment.
From Sanford Underground Research Facility, May 19, 2020: The international Deep Underground Neutrino Experiment, hosted by Fermilab, will be tuned to see neutrinos streaming from a nearby supernova. Such neutrino interactions could give researchers insight into one of the explosive processes that formed the elements in our solar system and our planet.
From Event Horizon podcast, March 19, 2020: Fermilab scientist James Annis and John Michael Godier discuss neutrinos, dark energy, dark matter and upcoming cosmological surveys in this 30-minute interview.
