Chemo-dynamical evolution of tidal dwarf galaxies. II. The long-term evolution and influence of a tidal field
Sylvia Ploeckinger, Simone Recchi, Gerhard Hensler +1
In a series of papers, we present detailed chemo-dynamical simulations of tidal dwarf galaxies (TDGs). After the first paper, where we focused on the very early evolution, we prese…
The formation of NGC 3603 young starburst cluster: "prompt" hierarchical assembly or monolithic starburst?
Sambaran Banerjee, Pavel Kroupa
The formation of very young massive clusters or "starburst" clusters is currently one of the most widely debated topic in astronomy. The classical notion dictates that a star clust…
Galactic rotation curves, the baryon-to-dark-halo-mass relation and space-time scale invariance
Xufen Wu, Pavel Kroupa
Low-acceleration space-time scale invariant dynamics (SID, Milgrom 2009a) predicts two fundamental correlations known from observational galactic dynamics: the baryonic Tully-Fishe…
Simulations on the survivability of Tidal Dwarf Galaxies
Sylvia Ploeckinger, Simone Recchi, Gerhard Hensler +1
We present detailed numerical simulations of the evolution of Tidal Dwarf Galaxies (TDGs) after they kinematically decouple from the rest of the tidal arm to investigate their surv…
Lessons from the Local Group (and beyond) on dark matter
Pavel Kroupa
(Abridged) The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology…
The Vast Polar Structure of the Milky Way Attains New Members
Marcel S. Pawlowski, Pavel Kroupa
The satellite galaxies of the Milky Way (MW) align with and preferentially orbit in a vast polar structure (VPOS), which also contains globular clusters, stellar and gaseous stream…
