Over the past decade, advancements have enabled the simulation of galaxy formation starting from cosmological initial conditions. Simultaneously, cosmological surveys have achieved percent-level accuracy in model fitting. However, many traditional modelling approaches either overlook or greatly simplify the complex astrophysical processes that govern galaxy formation. This creates challenges for cosmology, particularly at ‘small-scale’ regimes where galaxy formation significantly influences cosmic structure. As part of the Learning the Universe collaboration, I am working with a team to address this challenge by jointly modeling cosmic structure and galaxy formation. Together, we are developing innovative methods to integrate essential galaxy formation processes into cosmological inference pipelines.
