Peeking into the Origins of IceCube Neutrinos: I. Buried Transient TeV
  Miniburst Rates
  Any interpretation of the astrophysical neutrinos discovered by IceCube must
accommodate a variety of multimessenger constraints. We address implications of
these neutrinos being produced in transient sources, principally if buried
within supernovae so that gamma rays are absorbed by the star. This would
alleviate tension with the isotropic Fermi GeV background that >10 TeV
neutrinos rival in detected energy flux. We find that IceCube data constrain
transient properties, implying buried GeV-TeV electromagnetic emission near or
exceeding canonical SN explosion energies of ~10^51 erg, indicative of an
origin within superluminous SNe. TeV neutrino bursts with dozens of IceCube
events -- which would be of great use for understanding r-process
nucleosynthesis and more -- may be just around the corner if they are a primary
component of the flux.
