In this talk, I'll introduce my past work on using the measurements of the galaxy clustering at different redshifts to constrain the galaxy formation models and cosmology. In detail, I used the galaxy samples of different properties in SDSS-II/III from redshift z~0.1 to z=0.7 and measured both the redshift and projected space clustering. The observed galaxy clustering is explained using halo models to connect the galaxies to the underlying dark matter distribution. In this way, we are able to use the observed galaxies to study the dark matter halos and further constrain cosmology.
Bio: Prof. Hong Guo is a faculty member in the astrophysics division of Shanghai Astronomical Observatory (SHAO). He received his B.S. degree in astronomy from Peking University in 2005, and a PhD from Shanghai Astronomical Observatory in 2011. He was then a postdoctoral scholar at the Case Western Reserve University, and the University of Utah, before he became a research professor at the SHAO since 2015. His research interests include cosmology, large-scale structure and galaxy formation and evolution.
