Has neutrino redshift been observed?

Click For Summary
SUMMARY

Neutrinos emitted from supernovae, such as those from SN1987A, have not demonstrated observable redshift due to their proximity in the Large Magellanic Cloud. Current detection methods yield only a limited number of confirmed supernova neutrino events, primarily from nearby sources, which do not exhibit redshift. Despite advancements in detector technology, the challenge remains in isolating neutrinos from extragalactic supernovae, preventing the observation of redshift phenomena in these particles.

I understand that neutrinos are emitted when supernova explode. I presume that there are quite accurate models that predict the energies of those neutrinos at the time of emission.

Has the phenomenon of redshift been observed when those neutrinos are subsequently detected?

Detecting supernova neutrinos is hard. In fact, we only have a handful of confirmed supernova neutrino events which originated from SN1987A and this supernova occurred in the large magellanic cloud which is very close by and there is no redshift to speak of.

If we had a galactic supernova today, the detectors are much larger and we would see more events but this would still not show any redshift because it would still be in our galaxy.

There is currently no way of singling out neutrinos from an extragalactic supernova.
