Lyman-alpha Radiation Pressure in Dense Star Clusters: Implications for Star Formation and Winds at Cosmic Dawn
The study investigated how Lyman-alpha (Ly$\alpha$) radiation pressure affects star formation in dense, compact star clusters at cosmic dawn using radiation hydrodynamic simulations and post-processing. Results show Ly$\\alpha$ is a dominant feedback mechanism, capable of launching significant gas winds once star formation saturates, though its impact depends heavily on dust abundance.
