SUMMARY:The Cosmological Challenges of Dwarf Galaxies\, Special ASTRON
 OMY TALK\, Julio Navarro\, University of Victoria
DESCRIPTION:A prime challenge to our understanding of galaxy formation
  concerns the scarcity of dwarf galaxies compared with the numerous lo
 w-mass halos expected in the current LCDM paradigm. This is usually ac
 counted for by assuming that energetic feedback from evolving stars co
 nfines dwarf galaxy formation to relatively massive halos spanning a n
 arrow mass range. I will highlight a number of observations that may b
 e used to test this assumption and discuss the puzzles and challenges 
 that arise from this analysis.
