Abstract

By studying the properties of Lyman-alpha emitting galaxies found by HETDEX with SED fitting, we seek to create a predictive model of Lyman-alpha emission for these galaxies' analogs in the epoch of reionization. With such a tool, the attenuation of Lyman-alpha emission in the high-z universe can be used to measure the evolution of the IGM neutral fraction. In this talk, I will detail our ongoing effort to create a clean sample of LAEs from HETDEX emission line detections in GOODS-N.
