Capturing primordial non-Gaussian signatures in the late Universe by multi-scale extrema of the cosmic log-density field
Yun Wang, Ping He
We construct two new summary statistics, the scale-dependent peak height function (scale-PKHF) and the scale-dependent valley depth function (scale-VLYDF) of matter density, and fo…
Turbulence, Thermal Pressure, and Their Dynamical Effects on Cosmic Baryonic Fluid
Yun Wang, Ping He
We employ the IllustrisTNG simulation data to investigate the turbulent and thermal motions of the cosmic baryonic fluid. With continuous wavelet transform techniques, we define th…
Identifying Halos in Cosmological Simulations with Continuous Wavelet Analysis: The 2D Case
Minxing Li, Yun Wang, Ping He
Continuous wavelet analysis is gaining popularity in science and engineering for its ability to analyze data across spatial and scale domains simultaneously. In this study, we intr…
Turbulence revealed by wavelet transform: power spectrum and intermittency for the velocity field of the cosmic baryonic fluid
Yun Wang, Ping He
We use continuous wavelet transform techniques to construct the global and environment-dependent wavelet statistics, such as energy spectrum and kurtosis, to study the fluctuation…
