Understanding the cosmic acceleration with massive galaxy surveys 依托大规模星系巡天的宇宙加速膨胀机制研究

Abstract

The cosmic acceleration, first probed by observations of SNIa in 1998, is one of the most significant discoveries in modern sciences. In the past 25 years, extensive studies have been performed to unveil the physical origin of this surprising phenomenon, including studies on dark energy and modified gravity. In this talk, I will report the latest progress in this field, and focus on cosmological implications of large galaxy surveys including eBOSS, DESI and PFS.
