Title: Stirring-up the gas: aspects of the physics of galaxies 10 billion years ago
I will present results from observations of more than 50 galaxies as seen as they were 10 Gyrs ago with integral-field spectroscopy. Taking advantage of this large sample, I will 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.
