Abstract：The discovery of a Higgs boson at Europe's Large Hadron Collider Galaxy surveys can provide key information for cosmological studies through probes of baryonic acoustic oscillations (BAO) and redshift space distortions (RSD). In this talk, I will focus on dark energy and gravity tests on cosmological scales using BAO and RSD measurements derived from the BOSS DR12 and eBOSS DR14 quasar survey. I’ll also discuss how to maximise the information context that can be extracted from large galaxy surveys.
