The relevance of the cosmic microwave background for cosmology
Pavel Kroupa, Eda Gjergo, Nikolaos Samaras
Within the Hot Big Bang picture, as usually interpreted in the standard LCDM framework and its hierarchical scenario for elliptical galaxy assembly, the cosmic microwave background…
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 mmax-Mecl relation in the LEGUS clusters
Marie Zinnkann, Tereza Jerabkova, Zhiqiang Yan +6
The relation between the maximum stellar mass in a very young cluster (mmax) and the total stellar mass of the cluster (Mecl), known as the mmax-Mecl relation, remains debated in t…
Origin of open clusters revealed by the evolution of the m_maxM_ecl relation
J. W. Zhou, Sami Dib, Pavel Kroupa
Using the Gaia DR3 open cluster catalog, we identified the most massive star in each observed cluster. Examining the m_maxM_cluster relations across different age ranges, we fin…
Revisiting the missing mass problem in MOND for nearby galaxy clusters
Dong Zhang, Akram Hasani Zonoozi, Pavel Kroupa
In the framework of Milgromian dynamics (MOND), galaxy clusters are known to exhibit a residual missing mass problem, with the baryonic mass falling short of the dynamical mass by…
The Initial Mass Function as the Equilibrium State of a Variational Process: why the IMF cannot be sampled stochastically
Eda Gjergo, Zhiyu Zhang, Pavel Kroupa
The stellar initial mass function (sIMF) is often treated as a stochastic probability distribution, yet such an interpretation implies Poisson noise that is inconsistent with growi…
