Cosmological implications of the eBOSS DR16 observations

  • 2020年秋季

Title: 

Speaker: Gongbo Zhao, National Astronomical Observatories, Chinese Academy of Science

Host: Taotao Fang

Time: 14:30-16:30, Thursday, Sept 24

Location: Physics Building 552

Abstract: I will review the progress of the eBOSS galaxy survey, and present the data analysis and cosmological implications of the DR16 data sample, which includes ~1M spectra taken for the luminous red galaxies (LRGs), emission line galaxies (ELGs) and clustering quasars (QSOs). eBOSS allows for a multi-tracer analysis, which improves constraints on the RSD and primordial non-Gaussianty, due to a suppression of the cosmic variance on large scales. I’ll focus on the multi-tracer analysis between the LRGs and ELGs and discuss the cosmological result.


Bio: Gong-Bo Zhao joined NAOC in 2012 as a full professor, after working as a postdoc at University of Portsmouth and Simon Fraser University. Zhao has been working extensively on frontiers in cosmology, and in particular, he is interested in data analysis and cosmological implications of large galaxy surveys. As a working group co-chair, he has led the eBOSS team to accomplish the task of observations, data analysis and cosmological studies. Zhao has published over 130 papers in refereed journals, with a citation over 10000. Due to the academic excellency, he has won prestigious fellowships including the NSFC Distinguished Young Scholar and the Royal Society Newton Advanced fellowships.
