Mass modelling of dwarf spheroidal galaxies: the effect of unbound stars from tidal tails and the Milky Way
Jaroslaw Klimentowski, Ewa L. Lokas, Stelios Kazantzidis +3
We study the origin and properties of the population of unbound stars in the kinematic samples of dwarf spheroidal galaxies. For this purpose we have run a high resolution N-body s…
The importance of interloper removal in galaxy clusters: saving more objects for the Jeans analysis
Radoslaw Wojtak, Ewa L. Lokas
We study the effect of contamination by interlopers in kinematic samples of galaxy clusters. We demonstrate that without the proper removal of interlopers the inferred parameters o…
Interloper treatment in dynamical modelling of galaxy clusters
Radoslaw Wojtak, Ewa L. Lokas, Gary A. Mamon +3
The aim of this paper is to study the efficiency of different approaches to interloper treatment in dynamical modelling of galaxy clusters. Using cosmological N-body simulation of…
Kinematical and Dynamical Modeling of Elliptical Galaxies
G. A. Mamon, E. Lokas, A. Dekel +2
Elements of kinematical and dynamical modeling of elliptical galaxies (Es) are presented. In projection, NFW models resemble Sersic models, but with a very narrow range of shapes (…
