Splitting Rules from Kinematic Flow: Local Evolution and Emergent Time
Ji-Yuan Ke, Ping He
The differential equations satisfied by the wavefunction coefficients of conformally coupled scalars in a power-law cosmology can be recast as an iterative differential system of b…
CWTHF: Subhalo Identification with Continuous Wavelet Transform
Minxing Li, Yun Wang, Ping He
With advances in cosmology and computer science, cosmological simulations now resolve structures in increasingly fine detail. As key tracers of hierarchical structure formation, su…
The dynamical and thermodynamic effects of turbulence on the cosmic baryonic fluid
Yun Wang, Minxing Li, Ping He
Both simulations and observations indicate that the so-called missing baryons reside in the intergalactic medium known as the warm-hot intergalactic medium (WHIM). In this study we…
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…
