Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
Galaxies lacking dark matter in the Illustris simulation
Moritz Haslbauer, Joerg Dabringhausen, Pavel Kroupa +2
(Abridged) Any viable cosmological model in which galaxies interact predicts the existence of primordial and tidal dwarf galaxies (TDGs). In particular, in the standard model of co…
A common Milgromian acceleration scale in nature
Pavel Kroupa, Indranil Banik, Hosein Haghi +6
A central problem of contemporary physics is whether the law of gravity is non-Newtonian on galaxy scales. Rodrigues et al. argue that Milgromian gravitation, which solves the flat…
The formation of UCDs and massive GCs: Quasar-like objects for testing for a variable stellar initial mass function (IMF)
Tereza Jerabkova, Pavel Kroupa, Joerg Dabringhausen +2
The stellar initial mas function (IMF) has been described as being invariant, bottom heavy or top-heavy in extremely dense star burst conditions. To provide usable observable diagn…
The stellar and sub-stellar IMF of simple and composite populations
Pavel Kroupa, Carsten Weidner, Jan Pflamm-Altenburg +4
The current knowledge on the stellar IMF is documented. It appears to become top-heavy when the star-formation rate density surpasses about 0.1Msun/(yr pc^3) on a pc scale and it m…
