SUMMARY:The IceCube Puzzle\, Theory Seminar (High Energy/Cosmology)\, 
 Markus Ahlers\, Wisconsin IceCube Particle Astrophysics Center
DESCRIPTION:Astrophysical neutrinos are unambiguous tracers of hadroni
 c interactions of cosmic rays (CRs) in our Universe. With this in mind
 \, high energy neutrino astronomy has long been anticipated to help un
 cover the orgin of high energy CRs. The recent detection of a flux of 
 high-energy extra-terrestrial neutrinos by the IceCube Observatory is 
 an important step in this direction. However\, the low statistics and 
 angular resolution of the signal makes an identification of the neutri
 no sources challenging. I will review various scenarios for the IceCub
 e signal\, ranging from exotic PeV dark matter decay to the more conve
 ntional candiate sources of high energy CRs. I will finally discuss va
 rious multi-messenger observations that can help us to solve the IceCu
 be Puzzle.
