The Smallest Scale of Hierarchy Survey (SSH). II. Extended star formation and bar-like features in the dwarf galaxy NGC 3741: recent merger or ongoing gas accretion?

F. Annibali, C. Bacchini, G. Iorio +12

Using Large Binocular Telescope deep imaging data from the Smallest Scale of Hierarchy Survey (SSH) and archival Hubble Space Telescope data, we reveal the presence of two elongate…

Dynamics of binary black holes in low-mass young star clusters

Sara Rastello, Michela Mapelli, Ugo N. di Carlo +5

Young star clusters are dynamically active stellar systems and are a common birthplace for massive stars. Low-mass star clusters ( M) are more numerous than…

Intermediate mass black holes from stellar mergers in young star clusters

Ugo N. Di Carlo, Michela Mapelli, Mario Pasquato +8

Intermediate mass black holes (IMBHs) in the mass range bridge the gap between stellar black holes (BHs) and supermassive BHs. Here, we investigate…

Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties

Michela Mapelli, Marco Dall'Amico, Yann Bouffanais +8

We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamicall…

Effective N-body models of composite collisionless stellar systems

Carlo Nipoti, Giacomo Cherchi, Giuliano Iorio +1

Gas-poor galaxies can be modelled as composite collisionless stellar systems, with a dark matter halo and one or more stellar components, representing different stellar populations…

From hydrodynamics to N-body simulations of star clusters: mergers and rotation

Alessandro Ballone, Stefano Torniamenti, Michela Mapelli +5

We present a new method to obtain more realistic initial conditions for N-body simulations of young star clusters. We start from the outputs of hydrodynamical simulations of molecu…
