Dynamical Mass Estimates for Two Luminous Star Clusters in Galactic Merger Remnants [PDF]
, 2006 We present high-dispersion spectra of two extremely massive star clusters in galactic merger remnants, obtained using the UVES spectrograph mounted on the ESO Very Large Telescope.

Star clusters as age tracers of the age-metallicity relation of the small magellanic cloud [PDF]
, 2009 In my Thesis, I determined ages of Small Magellanic Cloud (SMC) star clusters that have formed during the galaxys entire lifetime.

Old star clusters in the FSR catalogue [PDF]
, 2010 We investigate the old star clusters in the sample of cluster candidates from the Froebrich, Scholz & Raftery (FSR) list. Based on photometry from the Two-Micron All-Sky Survey, we generated decontaminated colour-magnitude and colour-colour diagrams ...

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter
The Astrophysical Journal Letters, 2023 The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that supersonically induced gas objects (SIGOs)–which formed in the early Universe due to the supersonic relative motion of baryons and dark

Star clusters in unperturbed spiral galaxies [PDF]
, 2008 Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

Missing for 20 yr: MeerKAT Redetects the Elusive Binary Pulsar M30B
The Astrophysical Journal Letters, 2023 PSR J2140−2311B is a 13 ms pulsar discovered in 2001 in a 7.8 hr Green Bank Telescope observation of the core-collapsed globular cluster M30 and predicted to be in a highly eccentric binary orbit.

Rotation in Globular Cluster stars [PDF]
Astronomy & Astrophysics, 2003 We present a derivation of upper limits to the rotation of Main Sequence stars in three globular clusters using spectra obtained during time allocated to the ESO Large Programs 165-L0263 and 167.D-0173, with UVES at VLT2 (Kueyen). The stars analyzed in this work do not show any evidence of high values of rotational velocities as far as the outer layers

New Parameters for Star Cluster Dynamics: The Effect of Primordial Binaries and Dark Remnants
The Astrophysical Journal, 2023 By studying the normalized cumulative radial distribution (nCRD) of the stars in the central region of a Monte Carlo-simulated globular cluster, we recently defined three parameters able to pinpoint the stage of internal dynamical evolution reached by ...

Search for variable stars in globular clusters [PDF]
Symposium - International Astronomical Union, 1986 A program to search poorly studied southern globular clusters for variable stars is being carried out on the 1-m Yale telescope at CTIO. Recently two galactic bulge clusters of moderately high metallicity have been found to contain RR Lyrae variables; a cluster of similar metallicity a little farther from the galactic center apparently has none.

Contribution of globular clusters to halos [PDF]
, 2015 The contribution of massive star clusters to their hosting halo dramatically depends on their formation mechanism and their early evolution. Massive globular clusters in the Milky Way (and in other galaxies) have been shown to display peculiar chemical ...
