Why Do Dark Matter Haloes Die Together? The Causes of Halo Assembly Bias at Galaxy Masses

At a constant mass, old dark matter haloes and young dark matter haloes cluster differently from one another. This fact, known as "assembly bias," severely complicates the construction of mock catalogues and serves as a major challenge for structure formation models. In this talk, I test and synthesize the many competing explanations for this phenomenon into a single cohesive story with a strong focus on low mass haloes.
