Probing high-energy neutrinos associated with a blazar

Studying a high-energy neutrino that was observed by the IceCube Neutrino Observatory at the South Pole and that is believed to be intergalactic in origin has yielded some intriguing "new physics" beyond the Standard Model

NASA's Swift helps tie neutrino to star-shredding black hole

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, ...
