Emission Line Galaxies as a Distinct Tracer
Abstract
The Emission Line Galaxy (ELG) sample of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) is one of the two largest ELG catalogs to date with its 170,000 galaxies. Designed to probe galaxies at high redshift (0.6 < z < 1.1) and at high density, this program is a pathfinder to next generation spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI), which will probe 100 times more galaxies. In this talk, I will explain how the ELG photometric selection impacts the clustering signal and present the various analysis techniques developed to ensure robust cosmological measurements. To conclude, I will present the best estimates derived for the growth rate of structure and lessons for future galaxy surveys.
