A Photometric Survey of Globular Cluster Systems in Brightest Cluster Galaxies
The Astrophysical Journal Supplement Series, 2023 Hubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies and their distances

Dynamics of the Globular Cluster System Associated with M87 (NGC 4486). II. Analysis [PDF]
, 2001 We present a dynamical analysis of the globular cluster system associated with M87 (= NGC 4486), the cD galaxy near the dynamical center of the Virgo cluster.

THE FLATTENING OF GLOBULAR CLUSTERS [PDF]
The Astronomical Journal, 1983 In the three nearest luminous galaxies, the Milky Way System, the Andromeda Galaxy and NGC 5128 the brightest globular clusters are rounder than the faintest ones. On the other hand (contrary to some previous results) the flattening of individual LMC clusters is found to be independent of their luminosities.

Extensive Globular Cluster Systems Associated with Ultra Diffuse Galaxies in the Coma Cluster [PDF]
, 2017 We present Hubble Space Telescope (HST) imaging of two ultra diffuse galaxies (UDGs) with measured stellar velocity dispersions in the Coma cluster. The galaxies, Dragonfly 44 and DFX1, have effective radii of 4.7 kpc and 3.5 kpc and velocity dispersions

Intergalactic Globular Clusters [PDF]
Highlights of Astronomy, 2005 AbstractWe confirm and extend our previous detection of a population of intergalactic globular clusters in Abell 1185, and report the first discovery of an intergalactic globular cluster in the nearby Virgo cluster of galaxies. The numbers, colors and luminosities of these objects can place constraints on their origin, which in turn may yield new ...

The Astrophysical Journal, 2023 We present a photometric analysis of globular cluster 47 Tuc (NGC 104) using near-IR imaging data from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS), which is in operation at Gemini-South telescope.

Constraining Co-Varying Coupling Constants from Globular Cluster Age
Universe, 2023 Equations governing the evolution of a star involve multiple coupling constants. Thus, the time it spends as a main-sequence star can be expected to depend on whether or not such constants vary over the time scale of stellar evolution.

HST Imaging of the Globular Clusters in the Fornax Cluster: NGC 1399 and NGC 1404 [PDF]
, 1997 The Fornax cluster galaxies NGC 1399 and NGC 1404 are ideal for studying the effects of a cluster environment on globular cluster systems. Here we present new optical imaging of these two galaxies from both the Hubble Space Telescope's Wide Field and ...

New VVV Survey Globular Cluster Candidates in the Milky Way Bulge [PDF]
Monthly notices of the Royal Astronomical Society, 2017 It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major problems for finding globular ...
