Back to the Future: Estimating Initial Globular Cluster Masses from their Present Day Stellar Mass Functions [PDF]

open access: yes, 2015
We use N-body simulations to model the 12 Gyr evolution of a suite of star clusters with identical initial stellar mass functions over a range of initial cluster masses, sizes, and orbits.

Globular cluster ages [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
We review two new methods to determine the age of globular clusters (GCs). These two methods are more accurate than the classical isochrone fitting technique. The first method is based on the morphology of the horizontal branch and is independent of the distance modulus of the globular cluster.

Globular cluster mass-loss in the context of multiple populations [PDF]

open access: yes, 2015
Many scenarios for the origin of the chemical anomalies observed in globular clusters (GCs; i.e., multiple populations) require that GCs were much more massive at birth, up to $10-100\times$, than they are presently.

Globular Cluster Population of Hickson Compact Group 22a and 90c

open access: yes, 2001
We present the first measurement of the globular cluster populations of galaxies in Hickson compact groups, in order to investigate the effect of these high density environments on the formation and evolution of globular cluster systems. Based on V and R

MOCCA code for star cluster simulations – IV. A new scenario for intermediate mass black hole formation in globular clusters [PDF]

open access: yes, 2015
We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other ...

FSR584 - a new globular cluster in the Galaxy? [PDF]

open access: yes, 2007
We investigate the nature of the recently catalogued star cluster candidate FSR584, which is projected in the direction of the molecular cloud W3 and may be the nearest globular cluster to the Sun.

Mass to Luminosity Ratios of Some Clusters in the Large Magellanic Cloud [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1990
Luminosity profiles and dynamical parameters of 12 globular clusters in the Large Magellanic Cloud (SB(s)m) are obtained from the concentric aperture photoelectric photometry of 3 different aged clusters and the collected photometric data of 9 clusters ...

The Origin of the Large Magellanic Cloud Globular Cluster NGC 2005

open access: yesThe 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.

DARK MATTER HALOS IN GALAXIES AND GLOBULAR CLUSTER POPULATIONS [PDF]

open access: yes, 2014
We combine a new, comprehensive database for globular cluster populations in all types of galaxies with a new calibration of galaxy halo masses based entirely on weak lensing.

Accurate distances to Galactic globular clusters through a combination of Gaia EDR3, HST, and literature data [PDF]

open access: yes, 2021
We have derived accurate distances to Galactic globular clusters by combining data from the Gaia Early Data Release 3 (EDR3) with distances based on Hubble Space telescope (HST ) data and literature based distances. We determine distances either directly
