Summary
Some supernovae may produce slower jets, potentially explaining hypernovae. Researchers explored TeV neutrino signals from these jets, finding that Gigaton Cherenkov experiments could detect them from nearby galaxies.
Area of Science:
- Astrophysics
- Particle Physics
Background:
- Core-collapse supernovae type Ib/c can be associated with gamma-ray bursts and relativistic jets.
- A hypothesis suggests a larger fraction of supernovae produce slower jets, potentially explaining hypernovae and envelope ejection.
Purpose of the Study:
- To explore the TeV neutrino signatures expected from slower jets in supernovae.
- To calculate the detection rates of these neutrinos with upcoming Gigaton Cherenkov experiments.
Main Methods:
- Simulating TeV neutrino signals from hypothetical slower supernova jets.
- Estimating detection rates using parameters for future Gigaton Cherenkov detectors.
Main Results:
- Slower jets from supernovae produce distinct TeV neutrino signatures.
- Upcoming Gigaton Cherenkov experiments show potential for detecting these neutrinos.
Conclusions:
- Individual jetted supernovae may be detectable from nearby galaxies.
- Neutrino astronomy offers a new window into understanding supernova energetics and jet production.
