High-energy cosmic neutrinos: A unique window to the universe

The universe is a natural laboratory for investigating physics. The unique properties of neutrinos make them excellent cosmic messengers to explore astronomy, particle physics, and cosmology. The IceCube experiment discovered TeV-PeV neutrinos of cosmic origin. These neutrinos provide the only unobstructed view of cosmic accelerators that power the highest energy radiation from the universe while also offering a beam to study fundamental physics. Observations of high-energy cosmic neutrinos have yielded significant results in recent years, including the identification of extragalactic sources and emissions from the Galactic Plane, and the coming years are anticipated to mark a golden age for discoveries. In this talk, I will discuss ongoing efforts in neutrino source studies, the implications of the neutrino flavor composition, and the potential of probing dark matter and new physics. I will also remark on the detection prospects of the next-generation neutrino telescopes in addressing challenging questions.
