-body modelling of the ED-2 stream progenitor shows Gaia BH3's formation involved dynamical interactions

Daniel Marín Pina, Mark Gieles, Sara Rastello +3

Context. The Gaia collaboration announced the discovery of a binary of a massive black hole (33 M) with a low-mass giant star (Gaia BH3) in the ED-2 stellar stream. The pro…

Teen TITANS simulations -- I. Inefficient intermediate-mass black hole seeding via stellar collisions in young massive clusters

Benedetta Mestichelli, Sara Rastello, Michela Mapelli +2

Young massive clusters (YMCs) provide favorable environments for frequent stellar collisions, potentially leading to the formation of very massive stars (VMSs) and seeds of interme…

The formation of Gaia BH3

Daniel Marín Pina, Mark Gieles, Sara Rastello +1

The Gaia collaboration announced the discovery of a massive black hole (BH) with a low-mass giant star companion, Gaia BH3, located in the ED-2 stellar stream. The properties of Ga…

The boring history of Gaia BH3 from isolated binary evolution

Giuliano Iorio, Stefano Torniamenti, Michela Mapelli +15

Gaia BH3 is the first observed dormant black hole (BH) with a mass of M and represents the first confirmation that such massive BHs are associated with metal-…

Dynamical formation of Gaia BH3 in the progenitor globular cluster of the ED-2 stream

Daniel Marín Pina, Sara Rastello, Mark Gieles +3

Context. The star-black hole (S-BH) binary known as Gaia BH3, discovered by the Gaia Collaboration is chemically and kinematically associated with the metal-poor ED-2 stream in the…

The Dragon-II simulations -- I. Evolution of single and binary compact objects in star clusters with up to 1 million stars

Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +7

We present the first results of the \textsc{Dragon-II} simulations, a suite of 19 -body simulations of star clusters with up to stars, with up to of them initially…

Dynamics of binary black holes in young star clusters: the impact of cluster mass and long-term evolution

Stefano Torniamenti, Sara Rastello, Michela Mapelli +3

Dynamical interactions in dense star clusters are considered one of the most effective formation channels of binary black holes (BBHs). Here, we present direct body simulations…

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…

The impact of binaries on the evolution of star clusters from turbulent molecular clouds

Stefano Torniamenti, Alessandro Ballone, Michela Mapelli +5

Most of massive stars form in binary or higher-order systems in clumpy, sub-structured clusters. In the very first phases of their life, these stars are expected to interact with t…

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…

Evolution of fractality and rotation in embedded star clusters

Alessandro Ballone, Michela Mapelli, Ugo N. Di Carlo +3

More and more observations indicate that young star clusters could retain imprints of their formation process. In particular, the degree of substructuring and rotation are possibly…

Stellar Black Hole Binary Mergers in Open Clusters

S. Rastello, P. Amaro-Seoane, M. Arca-Sedda +3

In this paper we study the evolution of a primordial black hole binary (BHB) in a sample of over 1500 direct-summation body simulations of small-and intermediate-size isolated…

A MODEST review

Anna Lisa Varri, Maxwell Xu Cai, Francisca Concha-Ramírez +7

We present an account of the state of the art in the fields explored by the research community invested in 'Modeling and Observing DEnse STellar systems'. For this purpose, we take…
