Constraining high-energy neutrinos from choked-jet supernovae with IceCube high-energy starting events

Understand

Different types of core-collapse supernovae (SNe) have been considered as candidate sources of high-energy cosmic neutrinos.

• Stripped-envelope SNe, including energetic events like hypernovae and super-luminous SNe, are of particular interest.
• They may harbor relativistic jets, which are capable of explaining the diversity among gamma-ray bursts (GRBs), low-luminosity GRBs, ultra-long GRBs, and broadline Type Ib/c SNe.
• Using the six-year IceCube data on high-energy starting events (HESEs), we perform an unbinned maximum likelihood analysis to search for spatial and temporal coincidences with 222 samples of SNe Ib/c.
