IceCube : The Birth of Neutrino Astronomy

Astroparticle Physics revolves around phenomena that involve (astro)physics under the most extreme conditions. Cosmic explosions, involving black holes with masses a billion times greater than the mass of the Sun, accelerate particles to velocities close to the speed of light and display a variety of relativistic effects. Some of the produced high-energy particles are detected on Earth and as such can provide us insight in the physical processes underlying these cataclysmic events. Having no electrical charge and interacting only weakly with matter, neutrinos are special astronomical messengers. Only they can carry information from violent cosmological events at the edge of the observable universe directly towards the Earth. 
The South Pole houses the world's largest neutrino telescope, the IceCube Neutrino Observatory, with which a world wide search for high-energy neutrinos originating from cosmic phenomena has been initiated. 
In this talk I will present the underlying ideas of high-energy neutrino production in explosive cosmic phenomena and the IceCube detection principles. It will be shown how the combination of IceCube data with satellite observations opens up the possibility to identify high-energy neutrinos originating from transient cosmic events. Of these transient phenomena Gamma Ray Bursts are believed to be the most violent cosmic explosions and recent results will be presented. Also the observation, for the first time in history, of very energetic neutrinos witha most likely cosmic origin, will be addressed.
