Abstract:
Fuzzy dark matter (FDM), composed of ultralight bosons with masses 10^{-22} -- 10^{-19} eV, exhibits intricate wave-like structures and presents a compelling alternative to conventional cold dark matter. This talk highlights recent progress from our group at NTU, including studies on soliton random motion, multi-component FDM models, galactic disc heating, an accretion boosting mechanism for supermassive black hole seeds, the soliton-halo relation, and the formation and simulation of Milky Way-sized halos. I will also present a novel hybrid fluid-wave algorithm for solving the Schrödinger-Poisson equations. Finally, I will introduce several ongoing non-FDM projects leveraging the GPU-accelerated adaptive mesh refinement code GAMER.
