Constraints on high-energy neutrino emission from SN 2008D

Understand

SN 2008D, a core collapse supernova at a distance of 27 Mpc, was serendipitously discovered by the Swift satellite through an associated X-ray flash.

• Core collapse supernovae have been observed in association with long gamma-ray bursts and X-ray flashes and a physical connection is widely assumed.
• This connection could imply that some core collapse supernovae possess mildly relativistic jets in which high-energy neutrinos are produced through proton-proton collisions.
• The predicted neutrino spectra would be detectable by Cherenkov neutrino detectors like IceCube.
