Lower central dark matter densities in nearby galaxies than predicted by simulations
Yu Lei, Ling Zhu, Meng Yang +9
Baryonic feedback in hydrodynamical simulations is typically invoked to alleviate the core--cusp problem in dwarf galaxies. Yet baryonic processes also induce adiabatic contraction…
A Dark-matter Origin of Little Red Dots: Early Seeding and Super-Bondi Accretion
Hua-Peng Gu, Fangzhou Jiang, Xian Chen +2
The "Little red dots" (LRDs) are a population of accreting supermassive black holes (SMBHs) in the early Universe which often exhibit undermassive or even undetectable stellar host…
An Enhanced Isothermal Jeans Approach to Constraining Dark Matter Self-Interactions from Galactic Kinematics
Zixiang Jia, Fangzhou Jiang, Shubo Li +3
We present an improved semi-analytical model to predict density profiles of self-interacting dark matter (SIDM) halos and apply it to constrain the self-scattering cross section us…
Non-Equilibrium Relativistic Core Collapse of Self-Interacting Dark Matter Halos -- Limits On Seed Black Hole Mass
Hua-Peng Gu, Fangzhou Jiang, Xian Chen +1
Recent observations of supermassive black holes (SMBHs) at high redshifts pose challenges to standard seeding mechanisms. Among competing models, the collapse of self-interacting d…
