主讲人/Speaker:
Donglian Xu is a dedicated ‘cosmic ghost messengers’ hunter, who explores the Universe via the neutrino lens. She obtained her BS degree at the University of Science and Technology of China in 2008, PhD degree at U of Alabama-Tuscaloosa in 2015, and was a postdoc researcher at UW-Madison from 2015 to 2018. She has been conducting research on neutrino astrophysics using the IceCube Neutrino Observatory at the South Pole, contributing substantially to its discovery of the high-energy cosmic neutrinos. Upon returning to China, she proposed the TRIDENT neutrino telescope in the South China Sea, acts as the spokesperson, and led a successful site scouting expedition finding a viable site at a sea depth of 3.5km in 2021. She is a recipient of the NSFC Excellent Young Scholars Fund (Overseas) in 2018, a PI of MOST young scientist and NSFC general grants, and TRIDENT Phase-I grant. She has published more than 300 papers, with an h-index of 83.
讲座摘要/Abstract:
Since 2013, the IceCube Neutrino Observatory has detected a diffuse high-energy neutrino flux, with NGC 1068 emerging as the most significant identified source (4.2σ). While most of the flux is likely extragalactic, recent findings suggest a small portion originates from within our Galaxy. Among these detections are also the first astrophysical tau neutrinos and a Glashow resonance event, paving the way for precise astrophysical neutrino flavor ratio measurements, which are crucial for exploring new physics. To pinpoint the sources of IceCube’s flux and drastically improve all-flavor neutrino statistics, advanced next-gen neutrino telescopes are needed. In this talk, I will introduce the proposed TRIDENT project, a next-gen neutrino telescope in South China Sea, and highlight its innovative technologies. I will also briefly discuss recent efforts to trace the origin of Galactic cosmic rays via high-energy neutrinos and gamma-rays.
