Abstract |
The IDILICO project is an international collaboration aimed at studying the assembly of galaxy aggregations from high-resolution, N-body simulations in the framework of the CDM concordance cosmology. We have recently finished the construction of a realistic N-body model of a galaxy group specifically tailored for gaining understanding of the role of gravity on structure formation and galaxy evolution. A set of group simulations is being used in an investigation of measurement techniques for the quantity of intragroup light (IGL). We present evidence that IGL detection methods based on the distribution of luminosity perform poorly in detecting the unbound stars. We also comment the results of an examination of the constraints that the spin and halo concentration put on both the merger duration and the distribution of projected directions of the rotation axes of colliding disk galaxies.
