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.

Biography:

Zhao obtained his PhD at IHEP, CAS in 2007, and worked as a postdoc at Simon Fraser University and Portsmouth University before joining as a faculty member at NAOC in 2012. He has been extensively working on cosmological implications on galaxy surveys and published over 170 papers with more than 20, 000 citations.
