Mass distribution in nearby Abell clusters
Ewa L. Lokas, Radoslaw Wojtak, Stefan Gottloeber +2
We study the mass distribution in six nearby (z<0.06) relaxed Abell clusters of galaxies A0262, A0496, A1060, A2199, A3158 and A3558. Given the dominance of dark matter in galaxy c…
The Draco dwarf in CDM and MOND
Ewa L. Lokas, Gary A. Mamon, Francisco Prada
We present interpretations of the line-of-sight velocity distribution of stars in the Draco dwarf spheroidal galaxy in terms of CDM and MOND assuming constant mass-to-light ratio a…
Velocity moments of dark matter haloes
Radoslaw Wojtak, Ewa L. Lokas, Stefan Gottloeber +1
Using cosmological N-body simulations we study the line-of-sight velocity distribution of dark matter haloes focusing on the lowest-order even moments, dispersion and kurtosis, and…
The complex velocity distribution of galaxies in Abell 1689: implications for mass modelling
Ewa L. Lokas, Francisco Prada, Radoslaw Wojtak +2
The Abell 1689 galaxy cluster has recently become a subject of intensive study. Thanks to its intermediate redshift (z=0.183) its mass distribution can be reconstructed using numer…
Radial velocity moments of dark matter haloes
Radoslaw Wojtak, Ewa L. Lokas, Stefan Gottloeber +1
Using cosmological N-body simulations we study the radial velocity distribution in dark matter haloes focusing on the lowest-order even moments, dispersion and kurtosis. We determi…
