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…
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…
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 exceptional…
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…
Constraints on Lorentz-invariance violation in the neutrino sector from the ultrahigh-energy event KM3-230213A
Yu-Ming Yang, Xing-Jian Lv, Xiao-Jun Bi +1
Lorentz invariance is a fundamental symmetry of spacetime and serves as the cornerstone of modern physics, supporting the constancy of the speed of light. A crucial implication of…
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…
Interpreting the Extremely Diffuse Stellar Distribution of the Nube Galaxy through Fuzzy Dark Matter
Yu-Ming Yang, Zhao-Chen Zhang, Xiao-Jun Bi +1
Recent observations have uncovered a remarkably flat and extremely diffuse stellar distribution within the almost dark dwarf galaxy Nube, posing a challenge to the standard cold da…
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…
Constraints on Lorentz invariance violation from the LHAASO observation of GRB 221009A
Yu-Ming Yang, Xiao-Jun Bi, Peng-Fei Yin
In some quantum gravity (QG) theories, Lorentz symmetry may be broken above the Planck scale. The Lorentz invariance violation (LIV) may induce observable effects at low energies a…
