Title "Dwarf Galaxies as Cosmological Probes"

Abstract:  A prime challenge to our understanding of galaxy formation concerns the
scarcity of dwarf galaxies compared with the numerous low-mass halos
expected in the current ΛCDM paradigm. This is usually accounted for by
assuming that energetic feedback from evolving stars confines dwarf
galaxy formation to relatively massive halos spanning a narrow mass
range. I will highlight a number of observations that may be used to
test this assumption and discuss the puzzles and challenges that arise
from this analysis.
