New IceCube results next Thursday (June 29)

[mfb]

TL;DR

IceCube is a neutrino detector in Antarctica, looking for neutrino at the highest energies.

Join us to hear exciting IceCube results!

It'll involve neutrinos, but beyond that I don't know what it is about. It will be something important or they wouldn't make a press conference.

I don't expect a relation, but it's interesting that NANOGrav has some news the same day.

"the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrinos—tiny, ghostlike astronomical messengers. In an article to be published tomorrow, June 30, in the journal Science, the IceCube Collaboration, an international group of over 350 scientists, presents evidence of high-energy neutrino emission from the Milky Way.

The high-energy neutrinos, with energies millions to billions of times higher than those produced by the fusion reactions that power stars, were detected by the IceCube Neutrino Observatory, a gigaton detector operating at the Amundsen-Scott South Pole Station. . . . unlike the case for light of any wavelength, in neutrinos, the universe outshines the nearby sources in our own galaxy. . . .

Interactions between cosmic rays—high-energy protons and heavier nuclei, also produced in our galaxy–and galactic gas and dust inevitably produce both gamma rays and neutrinos. Given the observation of gamma rays from the galactic plane, the Milky Way was expected to be a source of high-energy neutrinos. “A neutrino counterpart has now been measured, thus confirming what we know about our galaxy and cosmic ray sources. . . “The improved methods allowed us to retain over an order of magnitude more neutrino events with better angular reconstruction, resulting in an analysis that is three times more sensitive than the previous search,” . . . .

The dataset used in the study included 60,000 neutrinos spanning 10 years of IceCube data, 30 times as many events as the selection used in a previous analysis of the galactic plane using cascade events. These neutrinos were compared to previously published prediction maps of locations in the sky where the galaxy was expected to shine in neutrinos."
