What created this ‘ghost particle’ from space found on Earth?
CNN — Last summer, scientists found a “ghost particle” called a neutrino in Antarctica. “We wanted to unravel what makes TXS 0506+056 special, to understand the neutrino creation process and to localize the emission site and studied a series of high-resolution radio images of the jet.” Researchers studied observations of the galaxy taken between 2009 and 2018 to understand the galaxy’s activity before and after the neutrino event, known as IceCube 170922A. Now, the researchers believe the cause of the neutrino was a collision within the galaxy of accelerated material, called a jet, close to a supermassive black hole. A blazar is a giant elliptical galaxy with two jets emitting light and particles moving close to the speed of light along the axis of the black hole’s rotation. “And it would be a breakthrough if our analysis had provided another candidate for a binary black hole jet source with two jets.” The 2018 neutrino was found by sensors deep in the Antarctic ice in the IceCube detector.
