About Me

Astrophysics, cosmology, and numerical analysis. My current works focus on investigating various properties of the large-scale structure of the Universe from cosmological simulations, with the goal of bridging theoretical models with sky surveys and offering insights into fundamental cosmic phenomena. For this, I proposed a series of novel summary statistics, including the environment-dependent Wavelet Power Spectrum (env-WPS), environment-dependent Wavelet Cross-Correlation (env-WCC), scale-dependent PeaK Height Function (scale-PKHF), and scaledependent VaLleY Depth Function (scale-VLYDF). By employing the env-WPS and env-WCC, I analyzed the spatial deviation between baryonic gas and dark matter, the turbulent behavior of baryonic gas, and baryonic feedback effects on matter distribution. I also investigated the potential of the scale-PKHF and scale-VLYDF in constraining primordial non-Gaussianity and cosmological parameters from late-time matter distribution, highlighting their superiority over the ordinary power spectrum and bispectrum.
