The role of active supermassive black holes in the production of high-energy neutrinos from outside the Milky Way seems to have been confirmed.
from outside the Milky Way seems to have been confirmed. For the second time, physicists have traced these so-called"ghost" particles to the heart of a galaxy across the chasm of intergalactic space.factories, and use the neutrinos' properties to understand their home environments.– aka Messier 77 or the Squid Galaxy – a beautiful barred spiral located around 47 million light-years away, close enough to see with a pair of binoculars.
This makes the new collection of data, obtained over a 10-year period by the IceCube Neutrino Observatory, an absolute treasure trove. frameborder="0″ allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen> To a neutrino, normal matter in the Universe may as well be smoke and shadows. This is why we call them ghost particles.
NGC 1068, as we have already noted, is an active galaxy. It's a barred spiral, like the Milky Way; unlike the Milky Way, the supermassive black hole at the heart of NGC 1068 is devouring matter at a furious rate from the space around it.
