The Lumina Project: The Demographics of Active Galactic Nuclei from Quasars to Little Red Dots at z ≥ 3

High-redshift active galactic nuclei (AGN) are powerful probes of early black-hole growth, galaxy formation, and the evolving intergalactic medium (IGM). We use Lumina, a cosmological radiation-hydrodynamic simulation spanning the epochs of hydrogen and helium reionization, which combines a large (500 cMpc)3 volume w...

Self-Interacting Dark Matter: From Particle Physics Theories to Structure Formation Simulations

We establish a unified theory-to-simulation framework for self-interacting dark matter (SIDM) that integrates three components: (i) a comprehensive, self-contained treatment of its particle-physics foundations and a broad range of model classes; (ii) a systematic, quantitative mapping from microscopic dark-sector physi...

Self-Interacting Dark Matter: From Particle Physics Theories to Structure Formation Simulations

We present a unified theory-to-simulation framework for self-interacting dark matter (SIDM), combining a self-contained introduction to its particle-physics foundations and representative benchmark models with an explicit, systematic mapping to simulation inputs and validated numerical implementations in the moving-mes...
