Winds and Outflows in Starburst Galaxies and AGN

Winds and outflows in starburst galaxies and AGN provide important information on the physics of the “central engine”, the presence and evolution of (nuclear) starbursts, and the metal enrichment of the nuclear environment and the intergalactic medium. Here, we concentrate on two examples, X-ray observations of the (U)LIRG NGC6240 and the BAL quasar APM08279+5255.
