Velázquez Física, Astronomía y Matemáticas METHODS: N BODY SIMULATIONS GALAXIES: INTERACTIONS GALAXIES: KINEMATICS AND DYNAMICS We carried out three self-consistent N-body simulations of galaxy mergers,with a cuspy dark matter profile, in order to study if the inner dark density slopeis preserved in the remnants. In these simulations the progenitors include botha stellar disk and an intrinsic angular momentum for the halos, unlike previoussimilar studies. The mass-ratios of progenitor galaxies are about 1:1, 1:3, and 1:10.We find that the initial cuspy density profile of the dark halos is preserved in theremnants for the cases considered here. 2006 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57142105 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.42 |
