GLOBULAR CLUSTER STREAMS AS GALACTIC HIGH-PRECISION SCALES—THE POSTER CHILD PALOMAR 5 [PDF]
Proceedings of the International Astronomical Union, 2015 Using the example of the tidal stream of the Milky Way globular cluster Palomar 5 (Pal 5), we demonstrate how observational data on tidal streams can be efficiently reduced in dimensionality and modeled in a Bayesian framework.

The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]
, 1997 A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these ...

Paving the way for the JWST: witnessing globular cluster formation at z > 3 [PDF]
, 2016 We report on five compact, extremely young ( 3, elusive even in the deepest blank fields. We discuss how proto-GCs might contribute to the ionization budget of the Universe and augment Lya visibility during reionization.

Gaia EDR3 view on galactic globular clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We use the data from Gaia Early Data Release 3 (EDR3) to study the kinematic properties of Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM) for 170 clusters, determine the PM dispersion profiles for more than 100 ...

The Origin of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1988 The purpose of this article is to review some recent attempts to understand the origin of globular clusters. To put this in perspective, it may help to recall the analogous problem of the origin of galaxies. This splits into two parts. First, given a proto-galaxy with a specified mass and radius, how does it collapse, form stars and settle into a state

The Origin of the Large Magellanic Cloud Globular Cluster NGC 2005
The Astronomical Journal, 2023 The ancient Large Magellanic Cloud (LMC) globular cluster NGC 2005 has recently been reported to have an ex situ origin, thus, setting precedents that the LMC could have partially formed from smaller merged dwarf galaxies.

APOGEE chemical abundances of globular cluster giants in the inner Galaxy [PDF]
, 2016 We report chemical abundances obtained by Sloan Digital Sky Survey (SDSS)-III/Apache Point Observatory Galactic Evolution Experiment for giant stars in five globular clusters located within 2.2 kpc of the Galactic Centre.

Motions of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1995 Absolute proper motions of seven globular clusters have been determined with respect to extragalactic references and with accuracies of ∼ 1 mas/yr. Derived quantities and qualitative implications are described.

The WAGGS project - I. The WiFeS Atlas of Galactic Globular cluster Spectra [PDF]
, 2017 We present the WiFeS Atlas of Galactic Globular cluster Spectra, a library of integrated spectra of Milky Way and Local Group globular clusters. We used the WiFeS integral field spectrograph on the Australian National University 2.3 m telescope to ...
