Animation Berkeley Lab researchers are part of an international team that reports a high-sensitivity measurement by underground CUPID-Mo experiment. Nuclear physicists affiliated with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) played a leading role in analyzing data for a demonstration experiment that has achieved record precision […]

NASA Hubble Space Telescope image of Galaxy NGC 1068 with its active black hole shown as an illustration in the zoomed-in inset. A new model suggests that the corona around such supermassive black holes could be the source of high-energy cosmic neutrinos observed by the IceCube Neutrino Observatory.

Exploded star blooms like a cosmic flower. Credit: NASA/CXC/U.Texas A recent study on ‘pre-supernova’ neutrinos—tiny cosmic particles that are extremely hard to detect—has brought scientists one step closer to understanding what happens to stars before they explode and die. The study, co-authored by postdoctoral researcher Ryosuke Hirai, from the ARC […]

Excavation activities for the Long-Baseline Neutrino Facility began with first blast on June 23. Workers inspect the space cleared by the blast 3,650 feet below ground at the Sanford Underground Research Facility in South Dakota. They will eventually excavate hundreds of thousands of tons of rock to make way for […]

The Russian RATAN-600 telescope helps to understand the origin of cosmic neutrinos. Credit: Daria Sokol/MIPT Press Office Russian researchers trace high-energy neutrino origins to black holes in far-off quasars. Russian astrophysicists have come close to solving the mystery of where high-energy neutrinos come from in space. The team compared the […]

Analog-to-digital convertors built to work at cryogenic temperatures, such as the prototype pictured here, will operate inside of liquid-argon chambers in the Deep Underground Neutrino Experiment.
