Title of Talk: **“IceCube and the Discovery of High-Energy Cosmic 
Neutrinos”***

*_Abstract:_*

The IceCube project has transformed a cubic kilometer of natural 
Antarctic ice into a neutrino detector. The instrument detects more than 
100,000 neutrinos per year in the GeV to PeV energy range. Among those, 
we have isolated a flux of high-energy cosmic neutrinos. I will discuss 
the instrument, the analysis of the data, the significance of the 
discovery of cosmic neutrinos, and the recent multimessenger observation 
of a flaring TeV blazar in coincidence with the IceCube neutrino alert 
IC170922. The large cosmic neutrino flux observed implies that the 
Universe’s energy density in high-energy neutrinos is the same as that 
in gamma rays, suggesting that the sources are connected and that a 
multitude of astronomical objects await discovery.
