What dwarf galaxies tell us about galaxy formation and cosmology
Michael Blanton (NYU)
Dwarf galaxies in the field might be the simplest systems
we have for testing galaxy formation physics: they are
isolated from major recent mergers, they have had very
little star-formation and remain mostly gas, and they are
all disks with no bulges and small amounts of dust. I discuss
their properties using a sample from the SDSS with follow-up
21cm observations. In addition, I use their Tully-Fisher
relationship and luminosity function to put quantitative
constraints on the mass of the dark matter particle.
