First galaxy–neutrino link: IceCube ties to lensed starburst galaxy

Summary

Story summary

IceCube detected neutrino IC 210922A on 22 September 2021 in Antarctica.
ALMA imaged dust-obscured galaxy JCMT0402-0424 (“Shadow Blaster”) at redshift 2.988.
It appears as four lensed images, and its gas-rich core forms hundreds of solar masses of stars annually.
Researchers estimate <=1 % chance of such a galaxy in the neutrino region and claim the first galaxy–neutrino link.
They note starbursts could supply 15-20 % of the diffuse neutrino flux, with no counterpart found.
