The spatial distribution of galaxies reveals a coherent structure at large scale. The analysis based on observational data from sky surveys has provided us accurate measurement of the cosmic distance scales through baryon acoustic oscillation (BAO), and linear growth rate through redshift space distortion (RSD) effect. I will introduce our recent works on the investigation of large-scale structure from ongoing and future surveys. In particular, I will focus on the galaxy redshift survey from Nancy Grace Roman Space Telescope and introduce its constraining power on the cosmological measurement. On the other hand, the large-scale structure at non-linear scale is also informative. However, extracting the information at this scale is challenging due to the non-linearity of the dark matter dynamics and galaxy formation process. I will introduce our emulator approach on the modeling of galaxy clustering at non-linear scale based on high resolution N-body simulations, and the latest result from the application to the data of massive galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS).
I am a postdoctoral fellow at University of Waterloo, working with Prof. Will Percival. Prior to that, I was a postdoctoral associate at Caltech/IPAC, working with Dr. Yun Wang. I obtained my PhD from New York University, supervised by Prof. Michael Blanton and Jeremy Tinker. My research is in the fields of cosmology and galaxy science, using methodologies from numerical simulation, statistical analysis, and observational data from galaxy surveys.
