Hubble Space Telescope observations of globular clusters (GCs) in the Antenn galaxy show clusters of clusters, or regions in the galaxy that span hundreds of parsecs, where many of the GCs are doomed to collide, and eventually merge. Several such objects appear likely to present a signicant range in ages, hence possibly metallicities, and their merger could plausibly lead to multi-metallic GCs. Here we explore this process with direct-summation N body simulations with GPU hardware. Our results… 
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
Globular clusters (GCs), the oldest stellar systems observed in the Milky Way, have long been considered single stellar populations. As such, they provided an ideal laboratory to understand stellar
Spatial and kinematic segregation in star-cluster merger remnants
Globular clusters that exhibit chemical and dynamical complexity have been suggested to be the stripped nuclei of dwarf galaxies(e.g. M54, ω Cen). We use N-body simulations of nuclear star clusters
A critical look at the merger scenario to explain multiple populations and rotation in iron-complex globular clusters
Merging has been proposed to explain multiple populations in globular clusters (GCs) where there is a spread in iron abundance (hereafter, iron-complex GCs). By means of N-body simulations, we
Second generation stellar disks in Dense Star Clusters and cluster ellipticities
Globular Clusters (GCs) and Nuclear Star Clusters (NSCs) are typically composed by several stellar populations, characterized by different chemical compositions. Different populations show different
The dynamical origin of multiple populations in intermediate-age clusters in the Magellanic Clouds
Numerical simulations were carried out to study the origin of multiple stellar populations in the intermediate-age clusters NGC 411 and NGC 1806 in the Magellanic Clouds. We performed NBODY6++
Tails and streams around the Galactic globular clusters NGC 1851, NGC 1904, NGC 2298 and NGC 2808
We present DECam imaging for the peculiar Galactic globular clusters NGC1851, NGC1904 (M79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an important contribution of
Membership and seismic analysis of red giants in open clusters, a study of M67, Ruprecht 147 and NGC2158.
Star clusters form via the gravitational collapse of molecular clouds, hence the stars they contain are dynamically linked. Stellar clusters provide an insight into star formation, an important
Stellar populations in star clusters
Stellar populations contain the most important information about star clus- ter formation and evolution. Until several decades ago, star clusters were believed to be ideal laboratories for studies of
Three candidate double clusters in the LMC: truth or dare?
The Large Magellanic Cloud (LMC) hosts a large number of candidate stellar cluster pairs. Binary stellar clusters provide important clues about cluster formation processes and the evolutionary
Na-O anticorrelation and HB - IX. Kinematics of the program clusters A link between systemic rotation and HB morphology?
We use accurate radial velocities for 1981 member stars in 20 Galactic globular clusters, collected within our large survey aimed at the analysis of the Na-O anti-correlation, to study the internal
