Maximal Starbursts: Theory & Reality

Radiation pressure from the absorption and scattering of starlight by dust grains may be the dominant feedback mechanism in starburst galaxies. I describe the conditions for which star formation in galaxies is effectively Eddington-limited and self-regulated. In this picture, starbursts may be thought of in analogy with individual radiation pressure supported massive stars. I present evidence for this picture on the galaxy scale, on the scale of individual star clusters, and on parsec scales around active galactic nuclei, by comparing directly with observations of extreme star-forming environments at low and high redshift.
