ABSTRACT: Both active star formation and supermassive black hole accretion can
drive very energetic winds that can expel large amount of gas out of
I will present some recent observational results illustrating the dramatic
effect that such winds can have on galaxy evolution.
In particular, in some cases these energetic winds can clean galaxies
of most of their gas content. This may result in a significant
suppression of star formation in galaxies.
However, I will also show that the gas expelled out of galaxies is not simply
lost, it can also undergo compression, fragementation and finally form new stars.
This is a completely new mode of star formation, occurring outside galactic
discs, and resulting in stars with very high velocities, potentially even
escaping the galaxy. I will shortly discuss the potential implications
of this new mode of star formation.
