SUMMARY:The IceCube high energy neutrino events: has neutrino astronomy fi
 nally arrived? - Prof. Kael Hanson (Brussels)

DESCRIPTION:One year ago\, the IceCube collaboration released the surprisi
 ng results of a search for ultrahigh energy neutrinos to an audience at Ne
 utrino 2012 in Kyoto: two events survived the background cuts.  These even
 ts do not appear to be a result of the GZK neutrino production mechanism\,
  but nevertheless clearly stand out from terrestrial neutrino backgrounds.
   In the ensuing months\, the collaboration has developed a novel analysis
  sensitive to events of the genre discovered.  When the box was opened\, 2
 6 more events appeared with overall characteristics different from all kno
 wn terrestrial backgrounds.  The IceCube detector and the mysterious new e
 vents will be discussed as well as future plans for neutrino astrophysics 
 at the South Pole site.
