The anatomy of Leo I: how tidal tails affect the kinematics
Ewa L. Lokas, Jaroslaw Klimentowski, Stelios Kazantzidis +1
We model the recently published kinematic data set for Leo I dSph galaxy by fitting the solutions of the Jeans equations to the velocity dispersion and kurtosis profiles measured f…
Tidal evolution of disky dwarf galaxies in the Milky Way potential: the formation of dwarf spheroidals
Jaroslaw Klimentowski, Ewa L. Lokas, Stelios Kazantzidis +2
We conduct high-resolution collisionless N-body simulations to investigate the tidal evolution of dwarf galaxies on an eccentric orbit in the Milky Way (MW) potential. The dwarfs o…
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 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…
