Title: Stirring Up the Gas: Star Formation and Powering High Pressures in galaxies 10 Billion 
Years Ago

Abstract:
I will present results from observations of more than 50 galaxies as seen as they were 9 to 12 
Gyrs ago with integral-field spectroscopy. Taking advantage of this large sample, I will first paint 
a brief picture of the very particular physical nature of these galaxies. These observations reveal 
a surprisingly high amount of random motions in the gas inside these galaxies. I will explain 
why this effect is real (not due to observational limitations) and why it is probably a 
consequence of the intense star formation in these objects, outlining why we conclude that star 
formation is self-regulated.
