Formation of Elliptical and S0 Galaxies by Close Encounters | | Thorsten Naab

29 Jul 1999 | | Subject: | astro-ph | | Affiliation: | MPIA Heidelberg, Germany | | Abstract: | We study a possible formation mechanism for elliptical/S0 galaxies using N-body simulations with GRAPE. A close galaxy encounter which does not lead to a merger can induce a strong bar in an initially axisymmetric disk. This bar is unstable against bending oscillations and loses angular momentum to the dark halo. After 6 Gyrs the remnant is spheroidal with a de Vaucouleurs-type surface profile and has ellipticities and rotation properties comparable to observed elliptical/S0 galaxies: the system rotates fast (v/sigma approx 1) and has disky isophotes. | | Source: | arXiv, astro-ph/9907417 | | Services: | Forum | Review | PDF | Favorites | |
