SUMMARY:The Physics of Starburst Galaxies\, Astronomy Colloquium\, Tod
d Thompson\, Ohio State
DESCRIPTION:Star formation in galaxies is regulated by feedback proces
ses. I
\ndiscuss the physics and implications of momentum injecti
on via
\nradiation pressure on dust grains and supernovae\, includ
ing
\npredictions for the galaxy-scale winds driven by rapidly sta
r-forming galaxies and the characteristic surface density of star form
ation in ultra-luminous infrared galaxies. I discuss the disruption o
f giant molecular clouds\, with implications for their star formation
efficiency. I also present constraints on the magnetic field and cosm
ic ray energy densities in starbursts derived from the far-infrared--r
adio correlation and the gamma-ray emission of the local starbursts M8
2 and NGC 253.
