Boosting Supermassive Black Hole Growth in the Early Universe by Fuzzy Dark Matter Solitons
H. -H. Sandy Chiu, Hsi-Yu Schive, Hsiang-Yi Karen Yang +2
Observations of massive supermassive black holes (SMBHs) in the early universe challenge existing black hole formation models. We propose that soliton cores in fuzzy dark matter (F…

Deciphering the Soliton-Halo Relation in Fuzzy Dark Matter
Pin-Yu Liao, Guan-Ming Su, Hsi-Yu Schive +3
Soliton cores at the center of fuzzy dark matter (FDM) halos provide a promising way to distinguish FDM from other dark matter models. However, the relation between solitons and th…

A Hybrid Scheme for Fuzzy Dark Matter Simulations Combining the Schrödinger and Hamilton-Jacobi-Madelung Equations
Alexander Kunkel, Hei Yin Jowett Chan, Hsi-Yu Schive +2
This paper introduces a hybrid numerical scheme for the fuzzy dark matter model: It combines a wave-based approach to solve the Schrödinger equation using Fourier continuations wit…
