Stellar population synthesis models with a physically varying IMF

Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa

Interpreting galactic luminosity requires assumptions about the galaxy-wide initial mass function (gwIMF), often assumed invariant in most stellar population synthesis (SPS) models…

The impact of a top-heavy IMF on the formation and evolution of dark star clusters

Ali Rostami Shirazi, Hosein Haghi, Akram Hasani Zonoozi +2

The Spitzer instability leads to the formation of a black hole sub-system (BHSub) at the center of a star cluster providing energy to luminous stars (LSs) and increasing their rate…

Direct N-body simulations of globular clusters -- III. Palomar\,4 on an eccentric orbit

Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa +2

Palomar 4 is a low-density globular cluster with a current mass in the outer halo of the Milky Way with a two-body relaxation time of the order of a Hubble…

The effect of primordial mass segregation on the size scale of globular clusters

Hosein Haghi, Seyed Mohammad Hoseini-Rad, Akram Hasani Zonoozi +1

We use direct -body calculations to investigate the impact of primordial mass segregation on the size scale and mass-loss rate of star clusters in a galactic tidal field. We run…

Direct -body simulations of globular clusters - II. Palomar 4

Akram Hasani Zonoozi, Hosein Haghi, Andreas H. W. Kuepper +3

We use direct -body calculations to study the evolution of the unusually extended outer halo globular cluster Palomar 4 (Pal~4) over its entire lifetime in order to reproduce it…
