Resumen
CRUZ, F. y VELAZQUEZ, H.. Two scenarios for the formation of cuspy density profiles in elliptical galaxies. Rev. mex. astron. astrofis [online]. 2005, vol.41, n.1, pp.25-29. ISSN 0185-1101.
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.
