Among star-forming galaxies there is a particular population whose spectra exhibit strong nebular emission lines. These galaxies will be the preferred targets of new-generation spectroscopic surveys as Euclid, DESI, 4-MOST and Subaru HSC-SSP. All these instruments will observe [OII], [OIII] and Hα emission-line galaxies up to redshift z~2 to trace their star formation history and to measure the baryon acoustic oscillation peak as standard ruler for distances. They will build detailed 3D maps of the Universe to probe its large scale structure and to unveil the nature of dark energy. Therefore, it is crucial to understand how to measure and precisely model the clustering properties of such galaxies and how they form, evolve and distribute within their host dark matter halos. We address these issues using state-of-the-art data and large-volume high-resolution cosmological simulations to prepare the clustering prospects for the new generation of optical and near-IR experiments.
