IceCube search for a correlation between galaxies and neutrinos
The IceCube Neutrino Observatory, embedded in a cubic kilometer of Antarctic ice, searches for weakly interacting particles called neutrinos that are able to travel undisturbed through the cosmos. Of interest are high-energy astrophysical neutrinos that can arise from cosmic ray interactions with matter or photons in astrophysical sources. So far, high-energy neutrino emission has been […]
IceCube hunt for neutrino emission from Seyfert galaxies bright in X-rays
Almost two years ago, the IceCube Neutrino Observatory at the South Pole announced evidence for high-energy neutrinos spewing from the “nearby” active galaxy NGC 1068. NGC 1068 is an active galactic nucleus (AGN) with a central, supermassive black hole that actively gobbles up surrounding matter. Classified as a Seyfert galaxy, NGC 1068 is not dominated […]
