Rapid Chemical Enrichment in the Early Universe from Feedback-Coupled Gravitational Collapse

Recent observations of high-redshift galaxies reveal chemical enrichment occurring earlier than predicted by traditional, weak-feedback models of galaxy formation. This work presents a large-scale theoretical simulation investigating whether rapid enrichment can arise naturally under standard cosmological assumptions when gravitational collapse is strongly coupled to stellar feedback processes. Using a globally coupled dynamical framework incorporating gravitational collapse, star formation feedback, supernova-driven enrichment, and radiative cooling, we demonstrate the emergence of nonlinear enrichment regimes characterized by early starburst activity and accelerated metallicity growth. These regimes stabilize without runaway behavior and do not require exotic physics or modifications to ΛCDM. The results show that feedback-amplified collapse provides a dynamically plausible pathway to early chemical maturity, offering a theoretical framework consistent with emerging high-redshift observations. This work supports a reassessment of enrichment timescales in early galaxy evolution and highlights the importance of nonlinear feedback dynamics in cosmic structure formation.
