Reconstruction of galaxy star formation histories from redshift eight to the present day
Abstract/Contents
- Abstract
- In this dissertation, I present a comprehensive analysis of the gravitational influence of dark matter on the formation of stars in the universe from the epoch of reionization to the present day. This analysis is the first to self-consistently link observations of galaxy stellar mass and star formation rates to dark matter halos in simulations to redshift 8, along with full estimates of uncertainties inherent to the method. This allows direct constraints on the average rate of star formation in galaxies as a function of halo mass and redshift. Derived quantities are also presented, including average star formation histories, stellar ages, the relationship between star formation and baryon accretion rates, the buildup of the intracluster light, and limits on current observational inconsistencies. As they are required for this process, new calibrations of halo mass functions, satellite halo fractions, halo mass accretion histories, halo merger rates, and the expected disruption rate of merging galaxies into the ICL are presented. Finally, this dissertation discusses future work made possible by this analysis, including the potential to constrain individual galaxies' variations from the average star formation rates presented.
