SUMMARY:Feedback in Faint Galaxies During the Peak Epoch of Star Forma
 tion\, Astronomy Colloquium\, Dawn Erb\, UW Milwaukee Physics Dept
DESCRIPTION:Because faint\, low mass galaxies are numerous at high red
 shifts\, their impact on the Universe is expected to be significant. T
 hey may host a substantial fraction of global star formation\, provide
  many of the energetic photons needed to reionize the universe\, and c
 ontribute to the enrichment of the intergalactic medium through the ex
 pulsion of metals in galactic outflows. Because of their faintness\, h
 owever\, the properties of these galaxies are difficult to determine. 
 I will discuss a variety of observations aimed at characterizing the p
 hysical conditions in low mass galaxies at redshifts z~2-3\, the peak 
 epoch of star formation in the Universe\, with particular emphasis on 
 the study of galactic outflows in faint galaxies.<br>
