Abstract

The first sources of ionizing radiation to condense out of the dark and neutral IGM sent ionization fronts sweeping outward through their surroundings, overtaking other primordial gas-clouds and photoevaporating them. Results are presented of the first gas dynamical simulations of this process, including radiative transfer, along with some observational diagnostics.
