Abstract
AbstractNumerical simulations of galaxy mergers are a powerful tool to study these fundamental events in the hierarchical builtup of galaxies. Recent progress have been made owing to improved modeling, increased resolution and large statistical samples. We present here the highest‐resolution models of mergers performed so far. The formation of a variety of substructures ranging from kinematically decoupled cores to globular‐like clusters is directly resolved. In a resolution study, we show that the large‐scale structure of elliptical‐like merger remnants can be affected by the resolution, and a too modest resolution may affect the numerical predictions on the properties of major merger remnants: understanding precisely which kind of event or succession of events has formed the various types of elliptical galaxies remains an open challenge.
