Query: Type IIn supernovae as sources of high energy neutrinos   It is shown that high-energy astrophysical neutrinos observed in the IceCube
experiment can be produced by protons accelerated in extragalactic Type IIn
supernova remnants by shocks propagating in the dense circumstellar medium. The
nonlinear diffusive shock acceleration model is used for description of
particle acceleration.
