Physicists Face the Age of the Neutron – Phys.org

From left, Matthew Frost and Leah Broussard of ORNL used the neutron scattering instrument at the Spallation Neutron Source to search for the neutron’s dark matter twin.

Study identifies tidal perturbation event that coincides with high-energy neutrino production – Phys.org

Intense radiation from the TDE debris disk around the black hole (center) heats the surrounding dust until it begins to radiate brightly in the infrared. This process is called echo dust. Credit: Scientific Communication Lab and DESY. High-energy neutrinos are very cool subatomic particles that are produced when very fast charged particles collide with other …
