"Shadow Bomber" Galaxy May Explain Part of the Origin of Cosmic Neutrinos

  • No comments
A high-energy neutrino event has led astronomers to a distant, dusty galaxy. ALMA observations and gravitational lensing have revealed a compact core where intense star formation is taking place, potentially turning the galaxy into a natural particle accelerator.

The source of the most energetic neutrino ever discovered may be surprising

Research by the KM3NeT collaboration suggests that the extreme neutrino detected in the Mediterranean Sea in 2023 did not come from a single event, but rather from a diffuse flux of particles generated in a population of active galactic nuclei known as blazars.
