Semi-analytic forecasts for JWST -- II. physical properties and scaling relations for galaxies at z = 4-10

Understand

The long-anticipated James Webb Space Telescope (JWST) will be able to directly detect large samples of galaxies at very high redshift.

• Using the well-established, computationally efficient Santa Cruz semi-analytic model, with recently implemented multiphase gas partitioning and H2-based star formation recipes, we make predictions for a wide variety of galaxy properties for galaxy populations at $z$ = 4-10.
• In this work, we provide forecasts for the physical properties of high-redshift galaxies and links to their photometric properties.
• With physical parameters calibrated only to $z\sim0$ observations, our model predictions are in good agreement with current observational constraints on stellar mass and star formation rate distribution functions up to $z \sim 8$.
