Comparison of simulations and semi-analytical model for WDM subhalo mass functions
Mizuki Ono, Takashi Okamoto, Shin'ichiro Ando +1
The Cold Dark Matter (CDM) model successfully explains large-scale structure formation, but challenges remain at smaller scales, leading to interest in Warm Dark Matter (WDM) as an…
Quantifying the Velocity Anisotropy Profile of Galaxy Clusters Using the Uchuu Cosmological Simulation
Mohamed H. Abdullah, Raouf H. Mabrouk, Tomoaki Ishiyama +2
Galaxy clusters are powerful laboratories for studying both cosmic structure formation and galaxy evolution. We present a comprehensive analysis of the velocity anisotropy profile,…
Evolution of clustering in cosmological models with time-varying dark energy
Tomoaki Ishiyama, Francisco Prada, Anatoly A. Klypin
Observations favor cosmological models with a time-varying dark energy component. But how does dynamical dark energy (DDE) influence the growth of structure in an expanding Univers…
A Semi-analytic Framework of Population III and Subsequent Galaxy Formation on Cosmological N-body Simulations
Tomoaki Ishiyama, Shingo Hirano
We develop a new semi-analytic framework of Population (Pop) III and subsequent galaxy formation designed to run on dark matter halo merger trees. In our framework, we consider the…
