Astronomers trace high-energy neutrino to distant 'Shadow Blaster' galaxy 11 billion light-years away
By
Robert Lea
Summary
Astronomers have traced a high-energy neutrino (a "ghost particle") detected by the IceCube Neutrino Observatory in 2021 back to its source: a gravitationally lensed, star-forming galaxy nicknamed "Shadow Blaster," located 11 billion light-years away. This marks the first time a dusty star-forming galaxy has been directly linked to a high-energy neutrino event. The neutrino traveled for roughly 11 billion years, originating when the universe was only about 3 billion years old. The discovery provides new insights into the extreme cosmic environments that produce such particles and opens a new window into multimessenger astronomy.
