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 rigorous solution to the superluminal issue in the diffusion equation
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +2
Superluminal propagation is an intrinsic problem in the diffusion equation and has not been effectively addressed for a long time. In this work, a rigorous solution to this issue i…
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…
Cosmic-ray deuteron excess from a primary component
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +2
The recent AMS-02 measurements of cosmic-ray (CR) deuteron fluxes suggest the presence of primary deuterons in quantities far exceeding predictions from Big Bang nucleosynthesis. T…
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…
