Gamma-Ray Emission from Quasars Extends Along Jets of Plasma

An international team of more than 200 researchers from 13 countries has demonstrated that the emission of very high-energy gamma-rays from quasars—galaxies with a highly energetic nucleus—is not focused in the region close to their central black hole but extends over several thousand light-years across jets of plasma.
