A team of astronomers has identified a remarkably bright, gravitationally-lensed, star-forming galaxy as the likely source of the high-energy neutrino event IC 210922A, detected by the IceCube Neutrino Observatory in 2021. The galaxy, nicknamed “Shadow Blaster,” is located about 11 billion light-years away, providing the most concrete observational evidence yet that populations of distant star-forming galaxies play a significant role in producing high-energy cosmic neutrinos.

"If confirmed, Shadow Blaster would be the first-ever individual dusty star-forming galaxy directly linked to a high-energy neutrino event."
