Dark matter halo mass density profiles around an accreting supermassive blackhole in the Schrödinger-Newton approach

We study how supermassive blackhole accretion affects the mass density profile of a fuzzy dark matter soliton core at the centre of a dark matter halo. The supermassive blackhole at the center of a galaxy was regarded as a point mass. The Schr\"{o}dinger-Newton equation for the scalar field was...

Zusammenfassung:We study how supermassive blackhole accretion affects the mass density profile of a fuzzy dark matter soliton core at the centre of a dark matter halo. The supermassive blackhole at the center of a galaxy was regarded as a point mass. The Schr\"{o}dinger-Newton equation for the scalar field was solved numerically. We find that the time-dependent perturbation has a significant squeezing effect on the soliton density profile, which both reduces the size of the core and increases the central density.
