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 na…
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…
Searching for Ultralight Dark Matter with M{ö}ssbauer Resonance
Peng-Long Zhang, Yu-Ming Yang, Xiao-Jun Bi +5
We investigate the feasibility of probing the interactions between ultralight scalar dark matter and atomic nuclei using a stationary Mössbauer spectroscopy scheme. The exceptiona…
Probing Lorentz Invariance Violation at High Energies Using LHAASO Observations of GRB221009A via DisCan Algorithm
Yu-Chen Hua, Xiao-Jun Bi, Yu-Ming Yang +1
The Lorentz invariance violation (LIV) predicted by some quantum gravity theories would manifest as an energy-dependent speed of light, which may potentially distort the observed t…
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…
