SUMMARY:Multi-messenger astronomy with high-energy neutrinos\, Network
  in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\,
  Anna Franckowiak\, DESY & U. of Bochum
DESCRIPTION:Cosmic rays are charged particles (mainly protons) that bo
 mbard the Earth from all directions reaching energies up to 10 million
  times what can be achieved by the most powerful man-made accelerator\
 , the LHC. Their origin is difficult to trace\, because cosmic rays ar
 e deflected by magnetic fields on their journey from their source to E
 arth. However\, cosmic rays produce gamma-ray photons and neutrinos in
  interactions with matter and photon fields in or close to their sourc
 e. Being neutral those secondary particles can travel undeflected and 
 ultimately point back to the source. While gamma rays are not solely p
 roduced in interactions of cosmic ray protons\, neutrinos provide a sm
 oking-gun signature for acceleration of protons (or heavier nuclei).

\nA diffuse flux of cosmic neutrinos was first discovered by the cub
 ic-kilometer-sized IceCube detector located at the South Pole in 2013.
  I will present the ongoing search for the origin of those neutrinos u
 sing multi- messenger studies and discuss promising candidate sources 
 with a focus on the new promising neutrino source class of tidal disru
 ption events.
