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 $M_{dyn}/L_I=26^{+7}_…
The radial acceleration relation and dark baryons in MOND
Amir Ghari, Hosein Haghi, Akram Hasani Zonoozi
Recent observations of rotationally supported galaxies show a tight correlation between the observed radial acceleration at every radius and the Newtonian acceleration generated by…
A new formulation of the external field effect in MOND and numerical simulations of ultra-diffuse dwarf galaxies application to NGC 1052-DF2 and NGC 1052-DF4
Hosein Haghi, Pavel Kroupa, Indranil Banik +7
The ultra-diffuse dwarf galaxy NGC 1052-DF2 (DF2) has ten (eleven) measured globular clusters (GCs) with a line-of-sight velocity dispersion of km/s ($σ=10.6…
Evolution of star clusters on eccentric orbits: semi-analytical approach
Hamid Ebrahimi, Hosein Haghi, Pouria Khalaj +2
We study the dynamical evolution of star clusters on eccentric orbits using a semi-analytical approach. In particular we adapt and extend the equations of EMACSS code, introduced b…
