A hidden galaxy from 11 billion years ago may hold clues to the origin of high-energy cosmic neutrinos.
Using ALMA, astronomers uncovered "Shadow Blaster" - a compact, dust-obscured starburst galaxy located within the localization region of the IceCube neutrino event IC 210922A. Thanks to gravitational lensing, researchers revealed an intense, gas-rich core where extreme star formation could generate the conditions needed to produce high-energy neutrinos. While the association is not yet confirmed, the [...]
