How fast is mass-segregation happening in hierarchical formed embedded star clusters?
R. Dominguez, M. Fellhauer, M. Blana +2
We investigate the evolution of mass segregation in initially sub-structured young embedded star clusters with two different background potentials mimicking the gas. Our clusters a…
Understanding the internal dynamics of elliptical galaxies without non-baryonic dark matter
J. Dabringhausen, P. Kroupa, B. Famaey +1
Assuming virial equilibrium and Newtonian dynamics, low-mass early-type galaxies have larger velocity dispersions than expected from the amount of baryons they contain. The convent…
Could Segue 1 be a destroyed star cluster? - a dynamical perspective
Raul Dominguez, Michael Fellhauer, Matias Blaña +5
We attempt to find a progenitor for the ultra-faint object Segue 1 under the assumption that it formed as a dark matter free star cluster in the past. We look for orbits, using the…
Co-orbiting satellite galaxy structures are still in conflict with the distribution of primordial dwarf galaxies
Marcel S. Pawlowski, Benoit Famaey, Helmut Jerjen +11
Both major galaxies in the Local Group host planar distributions of co-orbiting satellite galaxies, the Vast Polar Structure (VPOS) of the Milky Way and the Great Plane of Andromed…
