A prediction of the standard Λ cold dark matter cosmology is that dark matter (DM) haloes
are teeming with numerous self-bound substructure or subhaloes. The precise properties of …

Warm dark matter constraints using Milky Way satellite observations and subhalo evolution modeling

A Dekker, S Ando, CA Correa, KCY Ng - Physical Review D, 2022 - APS
Warm dark matter (WDM) can potentially explain small-scale observations that currently
challenge the cold dark matter (CDM) model, as warm particles suppress structure formation …

Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation

P Kroupa - Canadian Journal of Physics, 2015 - cdnsciencepub.com
According to modern theory, galactic evolution is driven by the dynamics of dark matter and
stochastic star formation, but galaxies are observed to be simple systems. The existence of …
