Universal depletion of metal-poor globular clusters in inner galaxy regions: Fossil record of black hole retention
Ali Rostami-Shirazi, Narges Rostami, Hosein Haghi +1
We analyzed the spatial distribution of globular cluster (GC) systems across 37 host galaxies in a two dimensional parameter space defined by projected galactocentric distance Rg a…
Origin of High Dark Remnant Fractions in Milky Way Globular Clusters: The Crucial Role of Initial Black Hole Retention
Ali Rostami-Shirazi, Holger Baumgardt, Akram Hasani Zonoozi +2
Comparing the dynamical and stellar masses of Milky Way (MW) globular clusters (GCs) reveals a discrepancy exceeding a factor of two. Since this substantial invisible mass is conce…
Dark Star Clusters or Ultra-Faint Dwarf galaxies? Revisiting UMa3/U1
Ali Rostami-Shirazi, Hosein Haghi, Akram Hasani Zonoozi +1
Owing to sparse spectroscopic observations, the classification of faint satellites as either dark matter-dominated dwarf galaxies or self-gravitating star clusters remains unresolv…
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…
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 $…
