Has JWST already falsified dark-matter-driven galaxy formation?
Moritz Haslbauer, Pavel Kroupa, Akram Hasani Zonoozi +1
The James Webb Space Telescope (JWST) discovered several luminous high-redshift galaxy candidates with stellar masses of at photometric red…
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…
The Escape of Globular Clusters from the Satellite Dwarf Galaxies of the Milky Way
Ali Rostami Shirazi, Hosein Haghi, Pouria Khalaj +2
Using numerical simulations, we have studied the escape of globular clusters (GCs) from the satellite dwarf spheroidal galaxies (dSphs) of the Milky Way (MW). We start by following…
The Kennicutt-Schmidt law and the main sequence of galaxies in Newtonian and Milgromian dynamics
Akram Hasani Zonoozi, Patrick Lieberz, Indranil Banik +2
The Kennicutt-Schmidt law is an empirical relation between the star formation rate surface density () and the gas surface density () in disc galaxies. The relatio…
IMF-induced intrinsic uncertainties on measuring galaxy distances based on the number of giant stars: the case of the ultra-diffuse galaxy NGC 1052-DF2
Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa
The surface brightness fluctuation (SBF) technique is one of the distance measurement methods that has been applied on the low surface brightness galaxy NGC 1052-DF2 yielding a dis…
Do ultra compact dwarf galaxies form monolithically or as merged star cluster complexes?
Hamidreza Mahani, Akram Hasani Zonoozi, Hosein Haghi +3
Some ultra-compact dwarf galaxies (UCDs) have elevated observed dynamical V-band mass-to-light () ratios with respect to what is expected from their stellar population…
