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…
SKA Sensitivity to Potential Radio Emission from Dark Matter Annihilation in Ursa Major III
Peng-Long Zhang, Xiao-Jun Bi, Qin Chang +2
The recently discovered stellar system, Ursa Major III/UNIONS 1, may be the faintest and densest dwarf spheroidal satellite galaxy of the Milky Way. Owing to its close proximity an…
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…
Impact of Parameters in the Blazar Jet Magnetic Field Model on Axion-Like Particle Constraints
Lin-Qing Gao, Xiao-Jun Bi, Jun Li +1
The interaction between axion-like particles (ALPs) and photons induces ALP-photon oscillations in astrophysical magnetic fields, leading to spectral distortions in the -ray spe…
Determination of dark matter distribution in Ursa Major III and constraints on dark matter annihilation
Yi Zhao, Xiao-Jun Bi, Su-Jie Lin +1
The recently discovered satellite dwarf galaxy Ursa Major III provides a promising opportunity to explore the signatures resulting from dark matter (DM) annihilation, due to its pr…
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…
Precise measurement of the cosmic-ray spectrum and by LHAASO -- connecting the Galactic to the extragalactic components

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…
Interpretation of AMS-02 beryllium isotope fluxes using data-driven production cross sections
Meng-Jie Zhao, Xiao-Jun Bi, Kun Fang +1
The Be isotopic measurements preliminarily reported by the AMS-02 Collaboration have reached an unprecedented energy of 12 GeV/. As secondary cosmic rays (CRs), the Be isotopes…
Possible spectral irregularities in the AMS-02 positron spectrum
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +2
The excesses in the electron and positron spectra observed by many experiments, such as PAMELA and AMS-02, have sparked significant theoretical investigation. It is not easy to dis…
Constraints on Axion-like Particles from the Observation of Galactic Sources by LHAASO
Jun Li, Xiao-Jun Bi, Lin-Qing Gao +3
High-energy photons may oscillate with axion-like particles (ALPs) when they propagate through the Milky Way's magnetic field, resulting in an alteration in the observed photon ene…
