Description
Nancy Grace Roman space telescope will conduct a High Latitude Spectroscopic Survey (HLSS) over 2000 square degrees at high redshift. I will introduce the flowdown of the Roman science objectives of galaxy and cosmology based on numerical simulations. With this reference model, we forecast the performance of the survey, including the galaxy type, number density, clustering property and measurement of the expansion history and structure growth history. It also enables an exploration of variation from the fiducial survey design, such as survey area, depth, completeness and purity for large scale structure analysis.
