A correlation predicting galaxies without dark matter
Michal BÃlek
The standard theory of galaxy formation predicts that all galaxies should contain dark matter, yet a handful of recently discovered galaxies appear to lack it, challenging our unde…

Deviations from the radial acceleration relation in the central galaxies of clusters, subclusters, and groups
Michal BÃlek, Florent Renaud, Srdjan SamuroviÄ
Most galaxies closely follow the radial acceleration relation (RAR), which tightly links the observed accelerations to those predicted by Newtonian gravity from visible baryonic ma…

Fornax dwarf spheroidal in MOND: its formation and the survival of its globular clusters
Michal BÃlek, Hongsheng Zhao
The Fornax dwarf spheroidal galaxy has five massive globular clusters (GCs). They are often used for testing different dark matter and modified gravity theories, because it is diff…
