Dust and Molecules in Early Galaxies: Prediction and Strategy for   Observations
  The interplay between dust and molecules is of fundamental importance in early galaxy evolution. First we present the prediction for the dust emission from forming galaxies. Then we discuss the observational strategy for molecules in early galaxies by infrared absorption lines of a bright continuum source behind the clouds. By combining these two approaches, we will be able to have a coherent picture of the very early stage of galaxy evolution.
