Lyman-alpha Pressure Strongly Enhances Pre-Supernova Feedback at Cosmic Dawn: The First Multi-Dimensional Lyman-alpha Radiation Hydrodynamics Simulations
Olof Nebrin, Aaron Smith, Garrelt Mellema +2
The dynamical role of Lyman- (Ly) radiation pressure feedback has been debated for nearly a century, with recent analytical and 1D numerical studies highlighting its potent…

Lyman- radiation pressure regulates star formation efficiency
D. Manzoni, A. Ferrara
Order-unity star formation efficiencies (SFE) in early galaxies may explain the overabundance of bright galaxies observed by JWST at high redshift. Here we show that Lyman- (Ly…

Is feedback-free star formation possible?
A. Ferrara, D. Manzoni, E. Ntormousi
It has been suggested that, if the free-fall time of star-forming clouds is shorter than the lifetime ( Myr) of massive stars exploding as supernovae (SN), a large frac…
