High proper motion white dwarfs and halo dark matter
Santiago Torres, Enrique Garcia-Berro, Andreas Burkert +1
The interpretation of the old, cool white dwarfs recently found by Oppenheimer et al. (2001) is still controversial. Whereas these authors claim that they have finally found the el…
Constraints of the Clumpyness of Dark Matter Halos Through Heating of the Disk Galaxies
E. Ardi, T. Tsuchiya, A. Burkert
Motivated by the presence of numerous dark matter clumps in the Milky Way's halo as expected from the cold dark matter cosmological model, we conduct numerical simulations to exami…
The Failure of Self-Interacting Dark Matter to solve the Overabundance of Dark Satellites and the Soft Core Question
Elena D'Onghia, Andreas Burkert
Self-interacting dark matter was proposed by Spergel & Steinhardt (2000) to alleviate two conflicts between Cold Dark Matter (CDM) models and observations. Firstly, CDM N-body simu…
The Validity of the Adiabatic Contraction Approximation for Dark Matter Halos
R. Jesseit, T. Naab, A. Burkert
We use high resolution numerical simulations to investigate the adiabatic contraction of dark matter halos with a Hernquist density profile. We test the response of the halos to th…
Collisional Stellar Dynamics, Gas Dynamics and Special Purpose Computing
R. Spurzem, J. Makino, T. Fukushige +6
Challenging stellar dynamical problems, such as the study of gravothermal oscillations in star clusters, have in the past initiated the very successful building of GRAPE special pu…
The Origin of the Correlation between the Spin Parameter and the Baryon Fraction of Galactic Disks
Andreas Burkert, Frank C. van den Bosch, Rob A. Swaters
The puzzling correlation between the spin parameter lambda of galactic disks and the disk-to-halo mass fraction fdisk is investigated. We show that such a correlation arises natura…
