SUMMARY:Galactic Winds: Lessons from Nearby Starbursts\, Astronomy Col
 loquium\, Jay Gallagher\, UW Astronomy Prof and Chair
DESCRIPTION:Gas outflows from galaxies are a key aspect of the feedbac
 k process. Winds act as a cosmic safety valve to limit star formation 
 while also injecting metals\, magnetic fields\, and cosmic rays along 
 with fast moving gas into their surroundings.  They also may provide a
  path for the escape of Lyman continuum photons through the hot\, high
 ly ionized wind material.  Studies of 3 nearby classic starburst galax
 ies with winds\, M82\, NGC 253\, and NGC 1569 offer new insights into 
 how how starburst winds are launched  and the conditions under which t
 hey break out.  I will review our work on this topic that has been lar
 gely based on observations obtained with WIYN and Hubble Space Telesco
 pe\, and also briefly describe work in progress with Ellen Zweibel and
  Tova Yoast-Hull to better understand cosmic ray interactions in these
  types of systems.
