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<br>
\ndiscuss the physics and implications of momentum injecti
 on via<br>
\nradiation pressure on dust grains and supernovae\, includ
 ing<br>
\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.<br>
