Gamma ray discovery could advance understanding of role of ultra-fast outflows in the evolution of galaxies

Using data gathered by the Large Area Telescope onboard NASA's Fermi Gamma-ray Space Telescope and a stacking technique combining signals too weak to be observed on their own, researchers detected gamma rays from UFOs -- ultra-fast outflows -- in several nearby galaxies, providing a basis for scientists to understand what happened in our own Milky Way galaxy.
