Neutrino Simulations for SN 2023ixf
Neutrinos emitted from a supernova can be simulated, see the article on astrobites and the paper [2306.14717] Low and High Energy Neutrinos from SN 2023ixf in M101.
About multi-messenger (for more information, see [2307.14559] TXS 0506+056 with Updated IceCube Data):
| event | SN 1987A | TXS 0506+056 |
|---|---|---|
| category | type II supernova | blazer |
| year | 1987 | 2017 |
| energy of cosmic neutrino | low (~10 MeV) | high (~100 TeV) |
| the first confirmed multi-messenger source | the first successful multi-messenger campaign involving follow-up observations by telescope worldwide |
This simulation followed the hypothesis “core-collapse supernovae (CC-SNe)”.
And the result of the paper:
- Low-energy neutrinos: Super-K reports no significant detection, which supports the conclusions of this paper. Also, this supernova would likely not be detectable by Hyper-K.
- High-energy neutrinos: IceCube reports no significant detection, which is probably because
- only a small fraction (less than about 10%) of the kinetic energy is used to accelerate particles.
- the jet lasts a long time.
- it is highly relativistic.
