Dynamical friction in dwarf galaxies
We present a simplified analytic approach to the problem of the spiraling of a massive body orbiting within the dark halo of a dwarf galaxy. This dark halo is treated as the core region of a King distribution of dark matter particles, in consistency with the observational result of dwarf galaxies having solid body rotation curves. Thus we derive a simple formula which provides a reliable and ge...

متن کاملNonlinear Dynamical Friction in a Gaseous Medium
Using high-resolution, two-dimensional hydrodynamic simulations, we investigate nonlinear gravitational responses of gas to, and the resulting drag force on, a very massive perturber Mp moving at velocity Vp through a uniform gaseous medium of adiabatic sound speed a∞. We model the perturber as a Plummer potential with softening radius rs, and run various models with differing A = GMp/(a 2 ∞rs)...
متن کاملDynamical Friction in a Gaseous Medium
Using time-dependent linear perturbation theory, we evaluate the dynamical friction force on a massive perturber Mp traveling at velocity V through a uniform gaseous medium of density ρ0 and sound speed cs. This drag force acts in the direction −V̂ , and arises from the gravitational attraction between the perturber and its wake in the ambient medium. For supersonic motion (M ≡ V/cs > 1), the en...
متن کاملDynamical Friction and Galaxy Merging Timescales
The timescale for galaxies within merging dark matter halos to merge with each other is an important ingredient in galaxy formation models. Accurate estimates of merging timescales are required for predictions of astrophysical quantities such as black hole binary merger rates, the build-up of stellar mass in central galaxies, and the statistical properties of satellite galaxies within dark matt...
