Description
The first stars, star clusters, and galaxies are expected to have formed in starbursts within low-mass halos at Cosmic Dawn. To test our understanding of Cosmic Dawn and ΛCDM, accurate predictions of their properties are crucial, especially as new high-redshift observations begin to emerge. Current cosmological simulations, are typically numerically expensive and lack either sub-parsec resolution or a realistic implementation of stellar feedback. I will present preliminary results from Anaxagoras, a novel semi-analytical model of starbursts at Cosmic Dawn. Unlike existing semi-analytical models, Anaxagoras adopts an ab initio approach, incorporating every major stellar feedback process without fine-tuning. While physically comprehensive, Anaxagoras is fast enough to run on a laptop. I will discuss the model's predictions for the properties of the first Pop III and Pop II star clusters and galaxies.
