A detached stellar-mass black hole candidate in the globular cluster NGC 3201 [PDF]
, 2018 As part of our massive spectroscopic survey of 25 Galactic globular clusters with MUSE, we performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction. In this cluster, we found one curious star at the main-sequence

The Globular Cluster Systems of Ultra-diffuse Galaxies in the Coma Cluster [PDF]
Astrophysical Journal, 2018 Ultra-diffuse galaxies (UDGs) are unusual galaxies with low luminosities, similar to classical dwarf galaxies, but with sizes up to ∼5 larger than expected for their mass.

The Relationship between Globular Cluster Mass, Metallicity, and Light-element Abundance Variations [PDF]
Astronomical Journal, 2019 We investigate aluminum abundance variations in the stellar populations of globular clusters using both literature measurements of sodium and aluminum and APOGEE measurements of nitrogen and aluminum abundances.

Binary black hole mergers from globular clusters: the impact of globular cluster properties [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The dense environment of globular clusters (GCs) can facilitate the formation of binary black holes (BBHs), some of which can merge with gravitational waves within the age of the Universe.

Globular cluster star classification: Application to M13 [PDF]
Serbian Astronomical Journal, 2013 Starting from recent determination of Fe, O, Na abundances on a restricted sample (N = 67) of halo and thick disk stars, a natural and well motivated selection criterion is defined for the classification globular cluster stars. An application is

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 ...

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.

Globular cluster candidates within the Fornax Cluster: Intracluster globulars? [PDF]
Astronomy & Astrophysics, 2003 We present the results of a search for globular clusters in the surroundings of 15 low surface brightness dwarf galaxies belonging to the Fornax Cluster, which was carried out on CCD images obtained with the C and T1 filters of the Washington photometric system.
