Just read the title and thought "Not now Cthulu, we've got enough going on"

Summary for those who won't fight through four blocking pop-ups to read the article:

When a high-energy particle (cosmic ray, say) hits ice, it creates an interaction cascade. (Think of what the Fly's Eye experiment sees, but in ice.) That interaction cascade creates (among other things) a radio signal. This detector is a radio detector under Antarctic ice, looking for exactly that.

The point is that, if a high-energy neutrino were to hit the ice, it could create the same kind of cascade, but it would make it much further into the ice. By having multiple detectors, they can pin down the location, and so they can try to tell the difference between "regular" cosmic rays and high-energy neutrinos.

The detector seems to be functioning as designed. They have seven candidate neutrino interactions.

Is it just ice? I thought most neutrino detectors were large underground pools of water. I mean ... tomāto/tomăto, yes, but is solid water better than liquid water?

Pluribus, be careful

> With a new data release expected soon, covering all five ARA stations over several years, the ARA team now anticipates up to seven candidate neutrino events.

I love the patience involved in this kind of science.

I was involved in this analysis if anybody has questions (though the student and postdoc did most of the real work)
