Two Scenarios for the Formation of Cuspy Density Profiles in Elliptical Galaxies. (2005). Revista Mexicana De Astronomía Y Astrofísica, 41(1), 25-29. https://astronomia.unam.mx/journals/rmxaa/article/view/2005rmxaa..41...25c
Abstract
We address the formation of cuspy density profiles, through N-body simulations, in two complementary scenarios: (1) a cold gravitational collapse around a preexisting supermassive black hole, and (2) an adiabatic growth of a central black hole in a relaxed stellar system obtained from a cold gravitational collapse. Both models lead to a density profile, ργ , with a similar power-law index, γ; however, they show kinematical and morphological differences.Similar Articles
