The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is an untargeted spectroscopic survey that aims to measure the expansion rate of Universe at $z \sim 2.4$ 1% precision for both $H(z)$ and $D_A(z)$. HETDEX in process mapping excess one million Lyman Alpha emitting (LAE) galaxies a similar number lower-z as tracer large-scale structure. success measurement predicated on post-observation...
