Testing modified gravity with dwarf spheroidal galaxies
Hosein Haghi, Vahid Amiri
The observed velocity dispersion of the classical dwarf spheroidal (dSph) galaxies of the Milky Way (MW) requires the Newtonian stellar mass-to-light () ratios in the range…
A Possible Solution for the M/L-[Fe/H] Relation of Globular Clusters in M31: A metallicity and density dependent top-heavy IMF
Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa
The observed mass-to-light () ratios of a large sample of GCs in M31 show an inverse trend with metallicity compared to what is expected from Simple Stellar Population (SSP) m…
Declining rotation curves of galaxies as a test of gravitational theory
Hosein Haghi, Amir E. Bazkiaei, Akram Hasani Zonoozi +1
Unlike Newtonian dynamics which is linear and obeys the strong equivalence principle, in any nonlinear gravitation such as Milgromian dynamics (MOND), the strong version of the equ…
The Binary Fraction and Mass Segregation in Alpha Persei Open Cluster
Najmeh Sheikhi, Maryam Hasheminia, Pouria Khalaj +3
We have obtained membership probabilities of stars within a field of radius around the centre of the open cluster Alpha Persei using proper motions and photometry fro…
