The Star Formation History and Dynamics of the Ultra-diffuse Galaxy Dragonfly 44 in MOND and MOG
Hosein Haghi, Vahid Amiri, Akram Hasani Zonoozi +3
The observed line-of-sight velocity dispersion of the ultra diffuse galaxy Dragonfly 44 (DF44) requires a Newtonian dynamical mass-to-light ratio of $M_{dyn}/L_I=26^{+7}_…
The ultra-diffuse dwarf galaxies NGC 1052-DF2 and 1052-DF4 are in conflict with standard cosmology
Moritz Haslbauer, Indranil Banik, Pavel Kroupa +1
Recently van Dokkum et al. (2018b) reported that the galaxy NGC 1052-DF2 (DF2) lacks dark matter if located at Mpc from Earth. In contrast, DF2 is a dark-matter-dominated dwar…
Galaxies lacking dark matter in the Illustris simulation
Moritz Haslbauer, Joerg Dabringhausen, Pavel Kroupa +2
(Abridged) Any viable cosmological model in which galaxies interact predicts the existence of primordial and tidal dwarf galaxies (TDGs). In particular, in the standard model of co…
