It is suggested that there have been at least two physically distinct epochs of massive cluster formation. The first generation of globular clusters may have formed as halo gas was compressed by shocks driven inward by ionization fronts generated during cosmic reionization at z ~ 6. On the other hand, a second generation of massive clusters might have been formed at later times by compression, and subsequent collapse, of giant molecular clouds. In some cases this compression may have been… 
Globular cluster formation from gravitational tidal effects of merging and interacting galaxies
We investigate the spatial, kinematic and chemical properties of globular cluster systems formed in merging and interacting galaxies using N-body-smoothed particle hydrodynamics (SPH) simulations.
Reconstructing galaxy histories from globular clusters
TLDR
Recent advances in understanding of the globular cluster systems of the Milky Way and other galaxies point to a complex picture of galaxy genesis driven by cannibalism, collisions, bursts of star formation and other tumultuous events.
On the formation of globular cluster systems in a hierarchical Universe
ABSTRA C T We have investigated the formation of globular cluster (GC) systems in the fiducial semianalytic model of galaxy formation of Cole et al., by assuming that GCs are formed at high redshifts
Age Estimates of Globular Clusters in the Milky Way: Constraints on Cosmology
TLDR
The 95% confidence level lower limit on the age of the Universe of 11.2 billion years means that the three fundamental observables in cosmology now independently support the case for a dark energy–dominated Universe.
TWO POPULATIONS OF MOLECULAR CLOUDS IN THE ANTENNAE GALAXIES
Super star clusters-extremely massive clusters found predominately in starburst environments-are essential building blocks in the formation of galaxies and thought to dominate star formation in the
Evidence for inhomogeneous reionization in the local Universe from metal-poor globular cluster systems
Exploiting a fundamental characteristic of galaxy assembly in thecold dark matter paradigm, the observed spatial biasing and kinematics of metal-poor globular star clusters are used to constrain the
Globular Clusters in Dwarf and Giant Galaxies
The luminosity distribution of globular clusters shows a dramatic dependence on parent galaxy luminosity. Dwarf galaxies contain far more faint globulars than do luminous galaxies. This difference is
Evolution of star cluster systems in isolated galaxies: first results from direct N-body simulations
The evolution of star clusters is largely affected by the tidal field generated by the host galaxy. It is thus in principle expected that under the assumption of an "universal" initial cluster mass
Early-type galaxies in low-density environments: NGC 6876 explored through its globular cluster system
We present the results of a photometric study of the early-type galaxy NGC 6876 and the surrounding globular cluster (GC) system. The host galaxy is a massive elliptical, the brightest of this type
New Members of the Cluster Family in Nearby Lenticular Galaxies
Using spectra obtained with the Keck I Telescope, we have demonstrated conclusively that the faint (23 ≤ V ≤ 24 mag) and unusually extended objects we discovered in Hubble Space Telescope images of
