Did a spaghettified star close to a supermassive black hole send out a high-energy neutrino?

In a new article in Nature Astronomy researchers at the Oskar Klein Centre participate in a study that connects an energetic ghost-particle trapped in the Antarctic ice with a shredded star in a distant galaxy.
