3-D Observations of the Outflow from an Active Galactic Nucleus

A Japanese team of astronomers, Including Masamune Oguri at Kavli IPMU, has used the Subaru Telescope to observe a distant gravitationally-lensed quasar and probed an active galactic nucleus in its central region. Looking through multiple sight lines, the astronomers obtained a 3-D view of the quasar and discovered complex small structures inside outflows from the galactic nucleus. These outflows will spread widely and eventually affect the evolution of the host galaxy.
