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 will also discuss how to maximise the information context that can be extracted from large galaxy surveys.
 赵公博：Gong-Bo Zhao is a professor at NAOC since 2012. He works extensively on data analysis and cosmological implications of large galaxy surveys including BOSS, eBOSS, DESI, PFS and so on, and is one of the leaders of the eBOSS collaboration since 2015. He has published over 120 papers in refereed journals, with a total citation over 9000. He found a first observation evidence of the dynamics of dark energy at a significance over the 3 sigma level, and performed the world’s largest computer simulations for a wide range of gravity models.
