The ART of Cosmological Simulations
Stefan Gottloeber, Anatoly Klypin
We describe the basic ideas of MPI parallelization of the N-body Adaptive Refinement Tree (ART) code. The code uses self-adaptive domain decomposition where boundaries of the domai…
The time-delay of the gravitationally lensed double quasar UM 673
T. A. Akhunov, R. W. Schmidt, O. Burkhonov +11
The paper has been withdrawn because double checking and comparison with other data sets after the original submission showed that a broken R-band filter at the Maidanak telescope…
Mass modelling of galaxy clusters via velocity moments
Ewa L. Lokas, Radoslaw Wojtak, Gary A. Mamon +1
We summarize the method of mass modelling of galaxy clusters based on reproducing the dispersion and kurtosis of the projected velocity distribution of galaxies. The models are par…
Low mass dark matter halos in voids
Stefan Gottloeber, Ewa Lokas, Anatoly Klypin
Using numerical simulations and the Sheth-Tormen approximation we study the mass function of dark matter halos in voids. We find that the void mass function is significantly lower…
