The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey. The kinematic diversity of stellar halos and the relation between halo transition scale and stellar mass
C. Pulsoni, O. Gerhard, M. Arnaboldi +14
In the hierarchical two-phase formation scenario, the extended halos of early type galaxies (ETGs) are expected to have different physical properties from those of the galaxies' ce…
Formation of ellipticals by unequal mass mergers
Thorsten Naab, Andreas Burkert
Collisionless N-body simulations of merging disk-galaxies with mass ratios () of 1:1, 2:1, 3:1, and 4:1 have been performed using direct summation with the special purpose hardw…
Dark Matter Scaling Relations
Paolo Salucci, Andreas Burkert
We establish the presence of a dark matter core radius, for the first time in a very large number of spiral galaxies of all luminosities. Contrary to common opinion we find that th…
The structure and evolution of weakly self-interacting cold dark matter halos
Andreas Burkert
The evolution of halos consisting of weakly self-interacting dark matter particles is investigated using a new numerical Monte-Carlo N-body method. The halos initially contain kine…
Gas Stripping of Dwarf Galaxies in Clusters of Galaxies
Masao Mori, Andreas Burkert
Many clusters of galaxies contain an appreciable amount of hot gas, the intracluster medium. As a consequence, gas will be stripped from galaxies that move through the inter cluste…
Fragmentation in Molecular Clouds: The Formation of a Stellar Cluster
Ralf Klessen, Andreas Burkert
The isothermal gravitational collapse and fragmentation of a molecular cloud region and the subsequent formation of a protostellar cluster is investigated numerically. The clump ma…
