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…
Sideband Structure of Axion Electrodynamics
Run-Min Yao, Xiao-Jun Bi, Peng-Fei Yin +1
We develop a Floquet--Bloch sideband formulation of the linearized Maxwell--axion system in a coherent periodic axion background. Linearizing around prescribed magnetic and axion f…
Evolution of Compact Stellar Systems in Ultralight Dark Matter Halos: Dependence on Stellar and Dark Matter Parameters
Yu-Ming Yang, Xiao-Jun Bi, Long Wang +1
Compact stellar systems are often used to place stringent constraints on the particle mass of ultralight dark matter (ULDM), as the heating effect induced by wave interference can…
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…
Nonlinear diffusive shock acceleration with upstream escape reproduces DAMPE observations
Han-Xiang Hu, Xing-Jian Lv, Xiao-Jun Bi +3
We develop a self-consistent nonlinear extension of diffusive shock acceleration that incorporates cosmic ray (CR) backreaction on the shock precursor together with a physically mo…
Resonant photon-axion conversion driven by axion dark matter oscillations
Run-Min Yao, Xiao-Jun Bi, Peng-Fei Yin +1
Wave propagation in periodically time-dependent media can exhibit driven mode conversion that is absent in static or adiabatic descriptions. We show that coherent axion dark matter…
