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…
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…
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…
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…
