The Gaia mission promises to deliver precision astrometry at an unprecedented level, heralding a new era for discerning the kinematic and spatial coordinates of stars in our Galaxy. Here, we present a new technique for estimating the age of tidally disrupted globular cluster streams using the proper motions and parallaxes of tracer stars. We evolve the collisional dynamics of globular clusters within the evolving potential of a Milky Way-like halo extracted from a cosmological $\Lambda$CDM…

Eight more low luminosity globular clusters in the Sagittarius dwarf galaxy
Context. The Sagittarius (Sgr) dwarf galaxy is merging with the Milky Way, and the study of its globular clusters (GCs) is important to understand the history and outcome of this ongoing process.
Identifying stellar streams in Gaia DR2 with data mining techniques
Streams of stars from captured dwarf galaxies and dissolved globular clusters are identifiable through the similarity of their orbital parameters, a fact that remains true long after the streams have
Revisiting the Fundamental Parameters of 49 New Star Clusters in Gaia DR2
Reliable fundamental parameters of star clusters such as distance modulus, metallicity, age, extinction, and binary fraction are of key importance for astrophysical studies. Although a lot of new
High-precision Dark Halo Virial Masses from Globular Cluster Numbers: Implications for Globular Cluster Formation and Galaxy Assembly
We confirm that the number of globular clusters (GCs), N$_{GC}$, is an excellent tracer of their host galaxy's halo virial mass M$_{vir}$. The simple linear relation M$_{vir} = 5 \times 10^9$


Tidal disruption of globular clusters in dwarf galaxies with triaxial dark matter haloes
We use N-body simulations to study the tidal evolution of globular clusters (GCs) in dwarf spheroidal (dSph) galaxies. Our models adopt a cosmologically motivated scenario in which the dSph is
Star Streams and the Assembly History of the Galaxy
Thin halo star streams originate from the evaporation of globular clusters and therefore provide information about the early epoch globular cluster population. The observed tidal tails from halo
Modeling the Disruption of the Globular Cluster Palomar 5 by Galactic Tides
The simulations unambiguously predict the destruction of Pal 5 at its next disk crossing in ~110 Myr, suggesting that many more similar systems could once have populated the inner parts of the Milky Way but have been transformed into debris streams by the Galactic tidal field.
Tidal Streams as Probes of the Galactic Potential
We explore the use of tidal streams from Galactic satellites for recovering the potential of the Milky Way. Our study is motivated both by the discovery of the first lengthy stellar stream in the
The origin of the Milky Way globular clusters
We present a cosmological zoom-in simulation of a Milky Way-like galaxy used to explore the formation and evolution of star clusters. We investigate in particular the origin of the bimodality
Destruction of the Galactic Globular Cluster System
We investigate the dynamical evolution of the Galactic globular cluster system in considerably greater detail than has been done hitherto, finding that destruction rates are significantly larger than
Dynamical Evolution of the Mass Function of Globular Star Clusters
We present a series of simple, largely analytical models to compute the effects of disruption on the mass function of star clusters. Our calculations include evaporation by two-body relaxation and
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 of
Accreted versus in situ Milky Way globular clusters
A large, perhaps dominant fraction, of the Milky Way’s halo is thought to be built-up by the accretion of smaller galaxies and their globular cluster (GC) systems. Here we examine the Milky Way’s GC
We present an extensive literature compilation of age, metallicity, and chemical abundance pattern information for the 41 Galactic globular clusters (GGCs) studied by Schiavon et al. Our compilation
