Neutrinos from Choked Jets Accompanied by Type-II Supernovae

Understand

The origin of the IceCube neutrinos is still an open question.

• Upper limits from diffuse gamma-ray observations suggest that the neutrino sources are either distant or hidden from gamma-ray observations.
• It is possible that the neutrinos are produced in jets that are formed in the core-collapsing massive stars and fail to break out, the so-called choked jets.
• We study neutrinos from the jets choked in the hydrogen envelopes of red supergiant stars.
