We present simulations of Lyman-α radiation transfer in an isolated disk galaxy with a turbulence subgrid model, multiphase interstellar medium and detailed star formation modeling. We investigate the influence of inclination on the observed Lyα properties for different snapshots. The Lyα spectrum, equivalent width distribution, and escape fractions vary significantly with the detailed morphology of the disk, leading to variations from one snapshot to another. In particular, we find that supernova-driven cavities near star-forming regions in the simulation can dominate the transmitted Lyα fraction, suggesting a variability of Lyman-α emitters on the timescales of the star formation activity.
Key words: galaxies: high-redshift / radiative transfer
