Self-interacting Dark Scalar Spikes around Black Holes via Relativistic Bondi Accretion
Wei-Xiang Feng, Alessandro Parisi, Chian-Shu Chen +1
We consider the spike mass density profile in a dark halo by self-consistently solving the relativistic Bondi accretion of dark matter onto a non-spining black hole of mass . We…

On the Dynamical Instability of Monatomic Fluid Spheres in (N+1)-Dimensional Spacetime
Wei-Xiang Feng
In this note, I derive the Chandrasekhar instability of a fluid sphere in (+1)-dimensional Schwarzschild-Tangherlini spacetime and take the homogeneous (uniform energy density)…

Dynamical Instability of Collapsed Dark Matter Halos
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
A self-interacting dark matter halo can experience gravothermal collapse, resulting in a central core with an ultrahigh density. It can further contract and collapse into a black h…
