Abstract

Dwarf galaxies dominate the galaxy luminosity function, yet their contribution to the baryonic mass function is not well determined. Photometric gas fraction estimators allow us to obtain neutral atomic gas masses for statistical samples of galaxies to help constrain the baryonic mass function. We adapt the photometric gas fraction technique to be more useful for predicting gas masses of dwarf galaxies.
