We present a new high-resolution N-body/smoothed particle hydrodynamics simulation of an encounter of two gas-rich disk galaxies that closely matches the morphology and kinematics of the interacting Antennae galaxies (NGC 4038/39). The simulation includes radiative cooling, star formation, and feedback from Type II supernovae. The large-scale morphology and kinematics are determined by the internal structure and the orbit of the progenitor disks. The properties of the central region, in…

From large scale gas compression to cluster formation in the Antennae overlap region
We present a detailed observational analysis of how merger-driven turbulence may regulate the star-formation efficiency during galaxy interactions and set the initial conditions for the formation of

Constrained simulations of the Antennae galaxies: comparison with Herschel-PACS observations
We present a set of hydro-dynamical numerical simulations of the Antennae galaxies in order to understand the origin of the central overlap starburst. Our dynamical model provides a good match to the
Spatially resolved star formation and fuelling in galaxy interactions

On the Origin of Diffuse Ionized Gas in the Antennae Galaxy
The "Antennae Galaxy" (NGC 4038/39) is the closest major interacting galaxy system and therefore often taken as merger prototype. We present the first comprehensive integral field spectroscopic

We present high resolution simulations of a multiple merger of three disk galaxies including the evolution of magnetic fields performed with the N-body/SPH code Gadget. For the first time, we embed
Mapping galaxy encounters in numerical simulations: the spatial extent of induced star formation
We employ a suite of 75 simulations of galaxies in idealized major mergers (stellar mass ratio ∼2.5:1), with a wide range of orbital parameters, to investigate the spatial extent of


Towards an accurate model for the Antennae galaxies
In the framework of hierarchical structure formation ellipticals can form from merging of smaller disk galaxies. The nearby interacting ‘Antennae’ galaxy pair (NGC 4038/39) is one of the best-studied

ABSTRA C T We discuss a heuristic model to implement star formation and feedback in hydrodynamical simulations of galaxy formation and evolution. In this model, gas is allowed to cool radiatively and
