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…
Ionising Feedback Effects on Star Formation in Globular Clusters with Multiple Stellar Populations
Asiyeh Yaghoobi, Joakim Rosdahl, Francesco Calura +2
Using 3D radiation-hydrodynamical simulations, we study the effects of ionising radiation on the formation of second-generation (SG) stars in Globular Clusters (GCs) with multiple…
Overestimated inclinations of Milgromian disc galaxies: the case of the ultradiffuse galaxy AGC 114905
Indranil Banik, Srikanth Togere Nagesh, Hosein Haghi +2
We present hydrodynamical star-forming simulations in the Milgromian dynamics (MOND) framework of a gas-rich disc galaxy with properties similar to AGC 114905, which has recently b…
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…
Stellar collisions in globular clusters: Constraints on the initial mass function of the first generation of stars
Sami Dib, Valery V. Kravtsov, Hosein Haghi +2
Globular clusters display an anticorrelation between the fraction of the first generation of stars () and the slope of the present-day mass function of th…
