The first two-dimensional radiation-hydrodynamic simulations prove that the radiation pressure in the Lyman-alpha (Lyα) line can exceed the direct stellar light force by up to 16 times and serve as the main feedback mechanism even before the explosion of supernovae in environments poor in dust. This

For decades astronomers puzzled over mysterious anti-correlations of light elements in globular clusters. New research based on high-resolution cosmological simulations shows: the chemical anomalies could have arisen long before the birth of the cluster's first stars—in giant gas clouds. This scenar
