The measurements of the Baryon Acoustic Oscillation (BAO) scale and the Redshift Space Distortion (RSD) from 3D galaxy maps have been tremendous success over the last decade. Ongoing and future galaxy redshift surveys including eBOSS, PFS, DESI, Euclid and WFIRST all target emission-line galaxies (ELGs) so that we can reach the universe at higher redshift.
One of the crucial step to make these surveys successful is to construct a realistic galaxy mock catalog against which a whole analysis pipeline would be tested and checked. Namely, we need to minimize a systematic error in constructing such a galaxy mock catalog. In particular, it is not entirely clear what is the best way to do so for ELGs. In this talk, we will discuss some challenges and possible routes to tackle this problem.
