galactic wind

(galactic superwind)
(wind of charged particles out of some galaxies)

The term galactic wind refers to a wind of charged particles (ions and/or electrons) moving out of a galaxy. The wind is generated by starbursts (significant star formation) or AGNs, and possibly other triggers. It is the mechanism of star formation feedback, presumably slowing the average star formation of a galaxy, limiting rapid star formation to occasional bursts.
