Dynamics of Wave Structures in Multifield Fuzzy Dark Matter Halos
Yu-Ming Yang, Xiao-Jun Bi, Peng-Fei Yin
As a natural extension of the single-field fuzzy dark matter (FDM) model, multifield FDM has attracted increasing attention in recent years. This scenario is motivated both by the…
Constraints on Self-Interacting Fuzzy Dark Matter from the Stellar Kinematics of the Dwarf Galaxy Leo II
Yi Zhao, Yu-Ming Yang, Xiao-Jun Bi +1
The one-parameter fuzzy dark matter (FDM) model has faced increasingly stringent constraints from both Lyman- forest observations and local measurements of dwarf galaxies. A nat…
Collapse versus Disruption: The Fate of Compact Stellar Systems in Ultralight Dark Matter Halos
Yu-Ming Yang, Xiao-Jun Bi, Long Wang +1
Interference of the ultralight dark matter (ULDM) field generates time-varying gravitational potential fluctuations, which stochastically heat stellar systems embedded in ULDM halo…
Tidal Suppression of Fuzzy Dark Matter Heating in Milky Way Satellite Galaxies
Yu-Ming Yang, Zhao-Chen Zhang, Xiao-Jun Bi +1
Many previous studies have imposed stringent constraints on the particle mass of fuzzy dark matter (FDM) by analyzing observations of Galactic satellite galaxies, which show no sig…
Construction of fuzzy dark matter halos with arbitrary initial velocities
Yu-Ming Yang, Xiao-Jun Bi, Peng-Fei Yin
Cosmological simulations of fuzzy dark matter (FDM) are computationally expensive, and the resulting halos lack flexibility in parameter adjustments, such as virial mass, density p…
Reproduction of NGC1052-DF4 by self-interacting dark matter: dark matter deficiency and tidal features
Zhao-Chen Zhang, Xiao-Jun Bi, Peng-Fei Yin
Observations of the velocity dispersion indicate a severe dark matter (DM) deficit in the ultra-diffuse galaxy, NGC1052-DF4 (DF4). The ultra-deep images obtained with the Gemini te…
A theoretical perspective on the almost dark galaxy Nube: exploring the fuzzy dark matter model
Yu-Ming Yang, Xiao-Jun Bi, Peng-Fei Yin
In recent astronomical observations, an almost dark galaxy, designated as Nube, has unveiled an intriguing anomaly in its stellar distribution. Specifically, Nube exhibits an excep…
Tidal Formation of dark matter deficit diffuse galaxy NGC1052-DF2 by SIDM
Zhao-Chen Zhang, Xiao-Jun Bi, Peng-Fei Yin
Observations have revealed a significant dark matter deficit in the ultra-diffuse galaxy NGC1052-DF2 (DF2). It is widely accepted that the formation of this unique galaxy can be at…
