I use numerical simulation to study and understand the Universe and everything inside. My researches in Astronomy can be roughly separated into three fields: cosmology, large-scale structure and galaxy cluster. At here, I give a brief description of what I have done. You can find more (mainly) on-going works at projects page.
For cosmology, I mainly focus on alternative cosmology models -- dark energy models, such as quintessence, coupled DE; modified gravity models, \gamma, f(R). My aim is using numerical simulation as an indicator to pin down or eliminate these alternative cosmology models.
For large-scale structures, I have worked on power spectrum, halo mass function, cosmology structures, such as cosmic webs.
For galaxy clusters, I am interesting in fossil group, ICL, and cluster properties.
In addition, I have worked a lot on mimicking multi-wavelength observations.
