In recent work, we have shown that it is possible to link quantitatively many aspects of damped Lyman α (DLA) absorbers in the spectra of quasars to high-resolution simulations of galaxy formation. Using runs from the same series of hydrodynamic numerical studies, we consider the expected properties of intrinsic Lyman α absorbers seen in the spectra of high-redshift (z > 2) gamma-ray burst afterglows (GRB–DLAs). If GRBs are associated with the death of massive stars, their afterglows provide…

The fraction of ionizing radiation from massive stars that escapes to the intergalactic medium
Whether stars could have driven the reionization of the intergalactic medium depends critically on the proportion of ionizing radiation that escapes the galaxies in which it is produced. Spectroscopy
Damped Lyman α absorbers as a probe of stellar feedback
We examine the abundance, clustering and metallicity of Damped Lyman- Absorbers (DLAs) in a suite of hydrodynamic cosmological simulations using the moving mesh code AREPO . We incorporate models of
