We (Aldana Grichener & Noam Soker) study high energy neutrino emission from relativistic jets launched by a black hole spiraling-in inside the envelope of a red supergiant, and find that such common envelope jets supernovae (CEJSNe) are a potential source for the ~10^15 eV neutrinos detected by IceCube.
