The VERITAS array has confirmed the detection of high-energy gamma rays from the vicinity of a supermassive black hole located in a distant galaxy, TXS 0506+056. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle that can be made at astrophysical sources of ultra-high energy cosmic rays.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich, provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

Three professors at The University of Alabama are part of an international team of scientists who found evidence of the source of tiny cosmic particles, known as neutrinos, a discovery that opens the door to using these particles to observe the universe.

For the first time, astrophysicists have localized the source of a cosmic neutrino originating outside the Milky Way. It is highly likely that the neutrino comes from a blazar in the Orion constellation. How did the scientists reach this interesting finding? They combined a neutrino signal from IceCube with measurements from other instruments, e.g. the Fermi-LAT and MAGIC telescopes. This multi-messenger observation provided a clue to an unsolved mystery: the origin of cosmic rays.
