Description
We present a new framework for constructing stellar halo density profiles from galaxy merger histories without relying on particle-based simulations. An approximate but efficient approach allows us to capture the essential physics of tidal stripping and orbit evolution for large ensembles of stellar halo models, making it well suited for statistical studies of halo structure and assembly. We have developed updated prescriptions for assigning stellar mass to progenitor halos and the growth of a massive stellar disk in the host. In this poster, we demonstrate that the resulting stellar halo density profiles are consistent with those found in previous theoretical and observational studies. We describe how our framework can be used to investigate the statistical properties of stellar haloes and their connection to galaxy assembly histories, ultimately for comparison to upcoming wide-field deep imaging surveys.
