SAURON's Challenge for the Major Merger Scenario of Elliptical Galaxy Formation
Andreas Burkert, Thorsten Naab, Peter H. Johansson
The intrinsic anisotropy delta and flattening epsilon of simulated merger remnants is compared with elliptical galaxies that have been observed by the SAURON collaboration, and tha…
Formation and evolution of galactic spheroids by mergers
Thorsten Naab, Andreas Burkert, Peter H. Johansson +1
Galactic spheroids can form as a result of galaxy interactions and mergers of disks. Detailed analyses of the photometric properties, the intrinsic orbital structure, the line-of-s…
Axisymmetric orbit models of N-body merger remnants: a dependency of reconstructed mass on viewing angle
J. Thomas, R. Jesseit, T. Naab +3
We model mock observations of collisionless N-body disc-disc mergers with an axisymmetric orbit superposition program that has been used to model Coma ellipticals. The remnants sam…
Influence of Orbital Behaviour and Chaos on the Shape of Dark Matter Halos
Andrea V. Maccio', Ioannis Sideris, Marco Miranda +2
It has been shown that the dissipative gas infall during galaxy formation has the capability to modify the shape of dark matter halos. In this paper we perform the first detailed a…
2-Dimensional Kinematics of Simulated Disc Merger Remnants
Roland Jesseit, Thorsten Naab, Reynier Peletier +1
We present a two-dimensional kinematic analysis for a sample of simulated binary disc merger remnants with mass ratios 1:1 and 3:1. For the progenitor discs we used pure stellar mo…
Orbital Structure of Collisionless Merger Remnants: On the Origin of Photometric and Kinematic Properties of Elliptical and S0 Galaxies
R. Jesseit, T. Naab, A. Burkert
We present a detailed investigation of the relation between the orbital content of merger remnants and observable properties of elliptical and S0 galaxies. Our analysis is based on…
