Conversations About Science with Theoretical Physicist Matt Stras*ler. “SEEING” DOUBLE: NEUTRINOS AND PHOTONS OBSERVED FROM THE SAME COSMIC SOURCE. There has long been a question as to what types of events and processes are responsible for the highest-energy neutrinos coming from space and observed by scientists.  Another question, probably related, is what creates the majority of high-energy cosmic rays been considerable hope of getting an answer to these question.  One of the things we’ve been awaiting (and been disappointed produces both high-energy photons and neutrinos at the same time, at a high enough rate that both types of particles can be observed at the In recent years, there has been some indirect evidence that blazars — narrow jets of particles, pointed in our general direction like the barrel of a gun, and created as material swirls near and almost into giant black holes in the centers of very distant galaxies — may be responsible for the high-energy neutrinos.  Strong direct evidence in favor of this hypothesis has just been presented today.   Last year, one of these blazars flared brightly, and the flare created both high-energy neutrinos and high-energy photons that were observed within the same period, coming from the same place in the sky. it’s a cubic kilometer of ice under the South Pole, instrumented with light detectors, and it’s ideal for observing neutrinos whose motion-energy far exceeds that of the protons in the Large Hadron Collider undetected, but one in 100,000 hits something, and debris from the collision produces visible light that Ice Cube’s detectors can record.   IceCube has already made important discoveries, detecting a new clas* of high-energy neutrinos On Sept 22 of last year, one of these very high-energy neutrinos was observed at IceCube. More precisely, a muon created underground by the IceCube.  To create the observed muon, the neutrino must have had a motion-energy tens of thousand times larger than than the
