NOvA far detector

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 Science, Oct. 2, 2020: As U.S. particle physicists start to drum up new ideas for the next decade in a yearlong Snowmass process they have no single big project to push for (or against). Physicists have just started to build the current plan’s centerpiece: The Long-Baseline Neutrino Facility at Fermilab will shoot particles through 1,300 kilometers of rock to the Deep Underground Neutrino Experiment in South Dakota. Fermilab Deputy Director of Research Joe Lykken and Fermilab scientist Vladimir Shiltsev comment on other possible pursuits in high-energy physics.

General relativity makes many incredible predictions, but one of the most amazing is how matter can warp space. Rapidly moving heavy objects like black holes can even cause ripples in space-time called gravitational waves. In this 13-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln tells us all about them.

When LIGO and Virgo detected the echoes that likely came from a collision between a black hole and a neutron star, dozens of physicists began a hunt for the signal’s electromagnetic counterpart.
