Reacción a "Reactions to the discovery of high-energy neutrinos emitted by an active galaxy"

This is, in my opinion, a major breakthrough in neutrino astronomy, robustly establishing the connection between AGNs [active galactic nuclei] and neutrino production. The statistical significance is good (although it can and will be improved).    

The IceCube result makes it possible to use a neutrino telescope to 'see', thanks to these particles, the vicinity of a supermassive black hole, hidden from conventional telescopes by huge clouds of dust and gas. The detection of 79 high-energy neutrinos in the gigantic device buried under the Antarctic ice is comparable to an X-ray, which allows us to see inside the 'patient', in this case, a super-active galaxy in the process of being devoured by a massive black hole.   

The study is of high quality (IceCube's trademark) and reinforces and expands on previous studies, opening a door to detailed observations of active galaxies.
