Mass modelling of Abell 2634: avoiding the interloper bias
Radoslaw Wojtak, Ewa L. Lokas
Using an example of the Abell 2634 galaxy cluster we discuss the effect of contamination of kinematic data by interlopers and its impact on mass modelling. The cluster data reveal…

The effect of unbound stars on the mass modelling of the Fornax dwarf
Ewa L. Lokas, Jaroslaw Klimentowski, Radoslaw Wojtak
We discuss how different approaches to selecting member stars in kinematic samples of dwarf spheroidal galaxies affect the estimates of their mass and anisotropy of stellar orbits.…

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…
