  IceCube is a cubic kilometer neutrino detector array in the Antarctic ice
that was designed to search for astrophysical, high-energy neutrinos. It has
detected a diffuse flux of astrophysical neutrinos that appears to be of
extragalactic origin. A possible contribution to this diffuse flux could stem
from core-collapse supernovae. The high-energy neutrinos could either come from
the interaction of the ejecta with a dense circumstellar medium or a jet,
emanating from the star's core, that stalls in the star's envelope. Here, we
will present results of a stacking analysis to search for this high-energy
neutrino emission from core-collapse supernovae using 7 years of $\nu_\mu$
track events from IceCube.
