We revisit the hypothesis that dense galactic nuclei are formed from inspiraling globular clusters. Recent advances in the understanding of the continuous formation of globular clusters over cosmic time and the concurrent evolution of the galaxy stellar distribution allow us to construct a simple model that matches the observed spatial and mass distributions of clusters in the Galaxy and the giant elliptical galaxy M87. In order to compare with observations, we model the effects of dynamical… Expand
Formation of globular cluster systems: from dwarf galaxies to giants
Globular cluster (GC) systems around galaxies of a vast mass range show remarkably simple scaling relations. The combined mass of all GCs is a constant fraction of the total galaxy mass and the meanExpand
Large scale kinematics and dynamical modelling of the Milky Way nuclear star cluster
Context. Within the central 10 pc of our Galaxy lies a dense cluster of stars. This nuclear star cluster forms a distinct component of the Galaxy, and similar nuclear star clusters are found in mostExpand
The Globular Cluster Migratory Origin of Nuclear Star Clusters
Nuclear Star Clusters (NSCs) are often present in spiral galaxies as well as resolved Stellar Nuclei (SNi) in elliptical galaxies centres. Ever growing observational data indicate the existence ofExpand
Nuclear Star Clusters in Cosmological Simulations
We investigate the possible connection between the most massive globular clusters, such as $\omega$ Cen and M54, and nuclear star clusters of dwarf galaxies that exhibit similar spreads in age andExpand
Dynamical Simulations of the First Globular Clusters
Tidally limited star clusters are started on nearly circular orbits in the dark matter sub-halos present at high redshift and evolved with an n-body code augmented with gravitational interactions inExpand
Disrupted globular clusters and the gamma-ray excess in the Galactic Centre
The Fermi Large Area Telescope has provided the most detailed view toward the Galactic Centre (GC) in high-energy gamma rays. Besides the interstellar emission and point-source contributions, theExpand
Gravitational wave sources from inspiralling globular clusters in the Galactic Centre and similar environments
We model the inspiral of globular clusters (GCs) towards a galactic nucleus harboring a supermassive black hole (SMBH), a leading scenario for the formation of nuclear star clusters.We consider theExpand
Star Clusters in Evolving Galaxies
Their ubiquity and extreme densities make star clusters probes of prime importance of galaxy evolution. Old globular clusters keep imprints of the physical conditions of their assembly in the earlyExpand
Globular cluster ejection, infall, and the host dark matter halo of the Pegasus dwarf galaxy
Recent photometric observations revealed a massive, extended (MGC ≳ 105 M⊙; Rh ∼ 14 pc) globular cluster (GC) in the central region (D3D ≲ 100 pc) of the low-mass (M* ∼ 5 × 106 M⊙) dwarf irregularExpand
The Coevolution of Nuclear Star Clusters, Massive Black Holes, and Their Host Galaxies
Studying how nuclear star clusters (NSCs) form and how they are related to the growth of the central massive black holes (MBHs) and their host galaxies is fundamental for our understanding of theExpand


Dynamical Evolution of Globular Clusters in Hierarchical Cosmology
We test the hypothesis that metal-poor globular clusters form within disk galaxies at redshifts z > 3. We calculate the orbits of model clusters in the time-variable gravitational potential of aExpand
Modeling the Metallicity Distribution of Globular Clusters
Observed metallicities of globular clusters reflect physical conditions in the interstellar medium of their high-redshift host galaxies. Globular cluster systems in most large galaxies displayExpand
Formation of Globular Clusters in Hierarchical Cosmology
We study the formation of globular clusters in a Milky Way-size galaxy using a high-resolution cosmological simulation. The clusters in our model form in the strongly baryon-dominated cores ofExpand
Dynamical Friction in dE Globular Cluster Systems
The dynamical friction timescale for globular clusters to sink to the center of a dwarf elliptical galaxy (dE) is significantly less than a Hubble time if the halos have King-model or isothermalExpand
Nuclear Star Clusters from Clustered Star Formation
Photometrically distinct nuclear star clusters (NSCs) are common in late-type disk and spheroidal galaxies. The formation of NSCs is inevitable in the context of normal star formation in which aExpand
The Coincidence of Nuclear Star Clusters and Active Galactic Nuclei
We study galaxies that host both nuclear star clusters and AGNs, implying the presence of a massive black hole. We select a sample of 176 galaxies with previously detected nuclear star clusters thatExpand
Globular Cluster System erosion in elliptical galaxies
Context. In this paper we analyze data of 8 elliptical galaxies in orde r to study the difference between their globular cluster systems (GCSs) radial distributions and those of the galactic stell arExpand

Globular cluster evolution is studied, modeling relaxation and energy exchange between the stars. A comprehensive survey is presented of Galactic globular cluster evolution until core collapse. MassExpand
Families of dynamically hot stellar systems over 10 orders of magnitude in mass
Dynamically hot stellar systems, whether star clusters or early-type galaxies, follow well-defined scaling relations over many orders of magnitudes in mass. These fundamental plane relations haveExpand
