An artist’s impression of a quasar wind (in light blue) being launched off of the accretion disk (red-orange) around a supermassive black hole. Inset at right are two spectra from the quasar SBS 1408+544, showing the leftward shift of absorbed light that revealed the acceleration of gas pushed by quasar winds.
