WebJun 13, 2024 · The empirical identification of the aspects of the galaxy–halo connection responsible for realistic size distributions – and correlations with velocity – will be of use in constraining such models and guiding the choice of inputs. WebJul 10, 2024 · Understanding the galaxy-halo connection is fundamental for contemporary models of galaxy clustering. The extent to which the haloes' assembly history and environment impact galaxy clustering (a.k.a. galaxy assembly bias; GAB), remains a complex and challenging problem. Using a semi-analytic galaxy formation model, we …
