Title: Physically Consistent Galaxy Stellar Masses and Star Formation Rates From z=0 to z=10
Cycle: 26

Abstract
We propose a forward modeling approach that will self-consistently combine multi-epoch and multi-waveband data and reduce uncertainties in recovering galaxy stellar masses and star formation rates from current ~0.35 dex levels to the 0.15 dex level or less, benefiting both observers and theorists. Key outcomes include: a fully physical, self-consistent picture of galaxy stellar masses and star formation histories from z=0 to 10; significantly reduced uncertainties on the evolution of galaxies in dark matter halos; mock catalogs for arbitrary current and future surveys that simultaneously match currently observed galaxy number densities, colors, and clustering; and public code to enable easy incorporation of future datasets as they become available.
