Fall 2023 Physics Colloquium:- Neutrino Astronomy- From Dream to Reality
The Universe has been studied using light since the dawn of astronomy, when starlight captured the human eye. The IceCube Neutrino Observatory, located at the geographic South Pole, observes the Universe in a different and unique way: in high-energy neutrinos. IceCube’s discovery in 2013 of a diffuse celestial neutrino radiation, in other words, high-energy neutrinos from beyond the solar system, started an era of neutrino astronomy. Searches for astronomical sources responsible for creating these neutrinos have covered broad source types while combating background event rates that are 6 orders of magnitude higher.
This year, we announced the observation of our very own Milky Way galaxy in neutrinos. This is the first non-electromagnetic observation of our galaxy. But why did it take 10 years to observe or own galaxy after observing extragalactic neutrinos? What makes neutrino astronomy difficult? These questions will be answered, and the state of neutrino astronomy and its place in multi-messenger astronomy will be reviewed.
