BLAZAR BRUNCH

Nov 25, 2025

We do not know everything that spews out of galactic jets, but we do know they produce cosmic rays and neutrinos. Because cosmic rays are charged particles, their paths are bent many different ways by intergalactic magnetic fields, and you cannot tell where they come from. But neutrinos have no charge, and they can travel as straight as a laser pointer.

Putting all this together with observations from gamma-ray satellites and gigantic ground-based neutrino detectors, astronomers were able to say that blazar TXS 0506+056 is a source of cosmic neutrinos and cosmic rays. For now, we can only speculate about the other particles generated in the blazar that never reach our detectors.
