Title: Finding groups/clusters in large galaxy redshift surveys

Speaker: Xiaohu Yang 杨小虎

Affiliation: Department of Astronomy, Shanghai Jiao Tong University

Host: Haoran Yu

Time: 14:30, Thursday, Oct 22

Location: Physics Building 552 (Online talk)

Abstract: I will talk about some background/history of large scale structure studies, the halo model, the basic frame work of the halo-based group finder we developed, some applications using galaxy groups. Then I will introduce the extended group/cluster finder that can be applied to both photometric and spectroscopic data, as well as the group catalogs we constructed from the current largest photometric redshift data: the DESI legacy imaging surveys DR8.
