Origin of the metal-rich vs. metal-poor globular clusters dichotomies in the Milky Way: A sign of low black hole natal kicks
Ali Rostami-Shirazi, Akram Hasani Zonoozi, Hosein Haghi +1
The bimodal metallicity distribution of globular clusters (GCs) in massive galaxies implies two distinct sub-populations: metal-poor and metal-rich. Using the recent data of \texti…
Has the Palomar 14 globular cluster been captured by the Milky Way?
Akram Hasani Zonoozi, Maliheh Rabiee, Hosein Haghi +1
We examine a new scenario to model the outer halo globular cluster (GC) Pal 14 over its lifetime by performing a comprehensive set of direct N-body calculations. We assume Pal 14 w…
The formation and evolution of dark star clusters II: The impact of primordial mass segregation
S. Mojtaba Ghasemi, Ali Rostami-Shirazi, Pouria Khalaj +2
We investigate the impact of primordial mass segregation on the formation and evolution of dark star clusters (DSCs). Considering a wide range of initial conditions, we conducted $…
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…
