Title: All about that Base: Baseline Metal Enrichment from Population III Star Formation in Cosmological Simulations
Cycle: 24
Abstract
We propose to use a new suite of mesoscale cosmological volume simulations with custom built sub-grid physics to study the baseline metal enrichment in the interstellar medium of the first galaxies resulting from Population III star formation. Determining this baseline metal enrichment will allow us to place a lower limit constraint on the UV spectral slope Beta due to metal enrichment, which can be directly applied to current and future frontier high redshift observations (i.e z>10). A robust lower limit on Beta allows us to place a lower limit on the local extinction value (i.e. dust) and thus the intrinsic luminosity and star formation rate of primordial galaxies.
