Self-regulated galaxy evolution within a self-consistently varying galaxy-wide IMF

Lukas Hof, Pavel Kroupa, Gerhard Hensler +1

Semi-analytical evolution models of galaxies are a useful and computationally inexpensive tool for fast assessment of individual properties and their evolution. In this work, speci…

The p-Laplacian as a Framework for Generalizing Newtonian Gravity and MoND

D. Scherer, J. Pflamm-Altenburg, P. Kroupa +1

The Radial Acceleration Relation (RAR) follows from Milgromian gravitation (MoND). Velocity dispersion data of many dwarf spheroidal galaxies (dSphs) and galaxy clusters have been…

Open star clusters and their asymmetrical tidal tails

Pavel Kroupa, Jan Pflamm-Altenburg, Sergij Mazurenko +4

Stars that evaporate from their star cluster by the energy equipartition process end up either in a leading or a trailing tidal tail. In Newtonian gravitation and for open star clu…

Mass segregation and velocity dispersion as evidence for a dark star cluster

Wenjie Wu, Pavel Kroupa, Jan Pflamm-Altenburg

A dark star cluster (DSC) is a system in which the cluster potential is dominated by stellar remnants, such as black holes and neutron stars having larger masses than the long-live…

The spin, expansion and contraction of open star clusters

Vikrant V. Jadhav, Pavel Kroupa, Wenjie Wu +2

Empirical constraints on the internal dynamics of open clusters are important for understanding their evolution and evaporation. High precision astrometry from Gaia DR3 are thus us…

The many tensions with dark-matter based models and implications on the nature of the Universe

Pavel Kroupa, Eda Gjergo, Elena Asencio +6

(Abridged) Fundamental tensions between observations and dark-matter based cosmological models have emerged. This updated review has two purposes: to explore new tensions that have…
