 題名“Neutrino Astronomy with IceCube at the Earth’s South Pole
 概要などThe Universe has been studied using light since the dawn of astronomy, when starlight captured the human eye. IceCube observes the universe in a different way, using high-energy neutrinos. Neutrinos are a necessary messenger in high-energy astronomy, and this talk will focus on resolving cosmic sources of astrophysical neutrinos. Most of the source search analyses rely on correlating with GeV gamma-rays, but no discoveries have been made to date, except for one strong evidence of a possible correlation. My talk will summarize the various source searches in IceCube, compare them to the observed diffuse cosmic flux of neutrinos, and argue on the need for multi-messenger astronomy beyond GeV gamma-rays in an attempt to draw a coherent picture that is the state of neutrino astronomy.
