Neutrino emission from a flaring blazar |
Seminar Title | Neutrino emission from a flaring blazar | | | Speaker: | Dr. XU Donglian | | | Affiliation: | (SJTU) | | | When | Thursday afternoon, Nov.8, 15:00 p.m. | | | Where: | Room 212, Astronomy Building | | Welcome to Attend | | | ( PMO Academic Committee & Academic Circulating committee) | | Abstract:In 2013, the IceCube Neutrino Observatory at the geographic South Pole detecteda diffuse astrophysical neutrino flux, marking the dawn of high-energy neutrino astronomy. Since then, the campaign of hunting for astrophysical neutrino sources has been on. On September 22, 2017, the IceCuberealtime alert system detected a 290 TeVmuon neutrinoevent, which triggered follow-up observations from more than 20 multi-wavelength telescopes around the world. The event was eventuallytraced back to a flaring blazar TXS0506+056, approximately 4 billion light years away. I will talk about the multi-messenger observation of the blazar neutrino event and its implications. |
