Gas Dynamics and Inflow in gas-rich Galaxy Mergers
Thorsten Naab, Andreas Burkert
We performed N-body/SPH simulations of merging gas-rich disk galaxies with mass ratios of 1:1 and 3:1. A stellar disk and bulge component and a dark halo was realized with collisio…
Statistical Properties of Collisionless Equal- and Unequal-Mass Merger Remnants of Disk Galaxies
Thorsten Naab, Andreas Burkert
We perform a large parameter survey of 112 collisionless N-body simulations of binary mergers of disk-galaxies with mass ratios of 1:1, 2:1, 3:1, and 4:1 using the special purpose…
Column Density Probability Distribution Functions in Turbulent Molecular Clouds: A Comparison between Theory and Observations
Andreas Burkert, Mordecai-Mark Mac Low
The one-point statistics of column density distributions of turbulent molecular cloud models are investigated and compared with observations. In agreement with the observations, th…
The Fundamental Line of the Local Group Satellites
Francisco Prada, Andreas Burkert
We present a new correlation between the mass-to-light (M/L) ratio and the mean metallicity for the satellites of the Local Group. This relation together with their central surface…
The Formation of the Milky Way in the Cosmological Context
Andreas Burkert
The formation of the Milky Way is discussed within the context of the cold dark matter scenario. Several problems arise which can be solved if the Galaxy experienced an early phase…
Star Formation in Turbulent Molecular Clouds
Andreas Burkert
Recent progress in the understanding of star formation is summarized. A consistent picture is emerging where molecular clouds form with turbulent velocity fields and clumpy substru…
