Young, wild and free: the early expansion of star clusters
Alessandro Della Croce, Emanuele Dalessandro, Alexander R. Livernois +1
Early expansion plays a fundamental role in the dynamical evolution of young star clusters. However, until very recently most of our understanding of cluster expansion was based on…
Shaping the unseen: the influence of baryons and environment on low-mass, high-redshift dark matter haloes in the SIEGE simulations
R. Pascale, F. Calura, A. Lupi +7
We use zoom-in, hydrodynamical, cosmological -body simulations tracing the formation of the first stellar clumps from the SImulating the Environments where Globular clusters Eme…
Exploring the Structures and Substructures of the Andromeda Satellite Dwarf Galaxies Cassiopeia III, Perseus I, and Lacerta I
Katherine L. Rhode, Nicholas J. Smith, Denija Crnojevic +8
We present results from wide-field imaging of the resolved stellar populations of the dwarf spheroidal galaxies Cassiopeia III (And XXXII) and Perseus I (And XXXIII), two satellite…
Effects of massive central objects on the degree of energy equipartition of globular clusters
Francisco I. Aros, Enrico Vesperini
We present an analysis of the degree of energy equipartition in a sample of 101 Monte Carlo numerical simulations of globular clusters (GCs) hosting either a system of stellar-mass…
The structural properties of multiple populations in the dynamically young globular cluster NGC 2419
Silvia Onorato, Mario Cadelano, Emanuele Dalessandro +3
NGC 2419 is likely the globular cluster (GC) with the lowest dynamical age in the Galaxy. This makes it an extremely interesting target for studying the properties of its multiple…
An ongoing tidal capture in the Large Magellanic Cloud: the low-mass star cluster KMK88-10 captured by the massive globular cluster NGC 1835?
Camilla Giusti, Mario Cadelano, Francesco R. Ferraro +6
In the context of a project aimed at characterizing the dynamical evolution of old globular clusters in the Large Magellanic Cloud, we have secured deep HST/WFC3 images of the mass…
Internal kinematics and structure of the bulge globular cluster NGC 6569
Cristina Pallanca, Silvia Leanza, Francesco R. Ferraro +8
In the context of a project aimed at characterizing the properties of star clusters in the Galactic bulge, here we present the determination of the internal kinematics and structur…
Empirical measurement of the dynamical ages of three globular clusters and some considerations on the use of the dynamical clock
Francesco R. Ferraro, Barbara Lanzoni, Enrico Vesperini +3
We have used the ``dynamical clock'' to measure the level of dynamical evolution reached by three Galactic globular clusters (namely, NGC 3201, NGC 6316 and NGC 6440). This is an e…
Ongoing hierarchical massive cluster assembly: the LISCA II structure in the Perseus complex
A. Della Croce, E. Dalessandro, A. Livernois +7
We report on the identification of a massive ( M) sub-structured stellar system in the Galactic Perseus complex likely undergoing hierarchical cluster assembly. S…
First observational evidence of a relation between globular clusters' internal rotation and stellar masses
M. Scalco, A. Livernois, E. Vesperini +3
Several observational studies have shown that many Galactic globular clusters (GCs) are characterised by internal rotation. Theoretical studies of the dynamical evolution of rotati…
Evolution of binary stars in the early evolutionary phases of ultra-faint dwarf galaxies
Alexander R. Livernois, Enrico Vesperini, Václav Pavlík
The dynamics of binary stars provides a unique avenue to gather insight into the study of the structure and dynamics of star clusters and galaxies. In this paper, we present the re…
New parameters for star cluster dynamics: the effect of primordial binaries and dark remnants
Bhavana Bhat, Barbara Lanzoni, Francesco R. Ferraro +1
By studying the normalized cumulative radial distribution (nCRD) of the stars in the central region of a Monte Carlo-simulated globular cluster, we recently defined three parameter…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XXIV. Differences in internal kinematics of multiple stellar populations
M. Libralato, E. Vesperini, A. Bellini +12
Our understanding of the kinematic properties of multiple stellar populations (mPOPs) in Galactic globular clusters (GCs) is still limited compared to what we know about their chem…
