Improving the open cluster census. II. An all-sky cluster catalogue with Gaia DR3 [PDF]
Astronomy & Astrophysics, 2023 Data from the Gaia satellite are revolutionising our understanding of the Milky Way. With every new data release, there is a need to update the census of open clusters. We aim to conduct a blind, all-sky search for open clusters using 729 million sources

Globular cluster system erosion and nucleus formation in elliptical galaxies [PDF]
, 1998 The radial distribution of globular clusters in galaxies is always less peaked to the centre than the halo stars'. Extending previous work to a sample of HST globular cluster systems in ellipticals, we evaluate the number of clusters lost to the galactic

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 ...

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.

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

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.

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 ...

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 ...

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

Evidence for an intermediate-mass black hole in the globular cluster NGC 6624 [PDF]
, 2017 PSR B1820−30A is located in the globular cluster NGC 6624 and is the closest known pulsar to the centre of any globular cluster. We present more than 25 yr of high-precision timing observations of this millisecond pulsar and obtain four rotational ...
