Abstract

Lyman-alpha based emission line surveys are prone to errors in their interpretation due to the complex radiative transfer for this line. We address this issue by running full radiative transfer simulations on the Illustris simulations and generate mock observations of Lyman-alpha emitters. Doing so, we can quantify two physical distortion effects in the two-point correlation function introduced by radiative transfer.
