Abstract
Neutrinos offer a unique window into some of the most energetic and distant phenomena in the Universe. The IceCube Neutrino Observatory at the South Pole is currently the world's largest neutrino detector, utilizing a cubic kilometer of Antarctic ice instrumented with thousands of optical sensors to detect Cherenkov radiation. In this talk, I introduce the science behind IceCube, detail the mechanisms of neutrino detection and reconstruction in ice, and highlight key discoveries—ranging from the identification of astrophysical neutrino sources to new constraints on fundamental particle physics.
I will also share insights and experiences from my two expeditions to the South Pole, where I contributed to the IceCube Upgrade project aimed at enhancing the observatory’s low-energy sensitivity and calibration. Finally, I provide an outlook on IceCube-Gen2, the next-generation observatory designed to significantly expand our scientific reach and open new frontiers in astroparticle physics.
