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 evolution of galaxy groups and of galaxies therein
Gary A. Mamon
Properties of groups of galaxies depend sensitively on the algorithm for group selection, and even the most recent catalogs of groups built from redshift-space selection should suf…
The highly obscured region around PKS1343-601 - I. Galactic interstellar extinctions using DENIS galaxy colours
A. C. Schroeder, G. A. Mamon, R. C. Kraan-Korteweg +1
The highly obscured radio-bright galaxy PKS1343-601 (l=309.7, b=+1.8) has been suspected to mark the centre of a hitherto unknown cluster in the Great Attractor region. As such it…
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 (…
Lost and found dark matter in elliptical galaxies
Felix Stoehr, Gary A. Mamon, Avishai Dekel +1
The kinematical properties of elliptical galaxies formed during the mergers of equal mass, stars+gas+dark matter spiral galaxies are compared to the observed low velocity dispersio…
