3 high-energy neutrinos were noticed touring in tandem.
The IceCube Neutrino Observatory in Antarctica detected the trio of lilliputian debris on February 17, 2016. That is the primary time the experiment has observed a triplet of neutrinos that all looked as if it would come from the similar position within the sky and inside 100 seconds of each other. Researchers file the in finding February 20 on arXiv.org.
Physicists nonetheless don’t know the place high-energy neutrinos are born. The 3 neutrinos’ proximity in time and area suggests the debris got here from the similar supply, equivalent to a flaring galaxy or an exploding big name. However the scientists couldn’t rule out the opportunity of a fluke — the triplet may merely were the results of unintended alignment between unassociated neutrinos.
8 other telescopes adopted up at the neutrino triplet, checking for some signal of the debris’ origins. The telescopes, which looked for gamma rays, X-rays and different wavelengths of sunshine, discovered not anything obviously related to the debris. However scientists have been in a position to rule out some imaginable explanations, like a within sight stellar explosion brought about by way of the cave in of a loss of life big name.
