The SLUGGS Survey: Measuring globular cluster ages using both photometry and spectroscopy
Christopher Usher, Jean P. Brodie, Duncan A. Forbes +4
Globular cluster ages provide both an important test of models of globular cluster formation and a powerful method to constrain the assembly history of galaxies. Unfortunately, mea…
Multiple Populations in Integrated Light Spectroscopy of Intermediate Age Clusters
Nate Bastian, Christopher Usher, Sebastian Kamann +9
The presence of star-to-star light-element abundance variations (a.k.a. multiple populations, MPs) appears to be ubiquitous within old and massive clusters in the Milky Way and all…
No evidence for intermediate-mass black holes in the globular clusters Cen and NGC 6624
Holger Baumgardt, Chenyu He, Sarah M. Sweet +8
We compare the results of a large grid of N-body simulations with the surface brightness and velocity dispersion profiles of the globular clusters Cen and NGC 6624. Our models…
Young star cluster populations in the E-MOSAICS simulations
Joel Pfeffer, Nate Bastian, J. M. Diederik Kruijssen +3
We present an analysis of young star clusters (YSCs) that form in the E-MOSAICS cosmological, hydrodynamical simulations of galaxies and their star cluster populations. Through com…
The search for multiple populations in Magellanic Clouds clusters - V. Correlation between cluster age and abundance spreads
S. Martocchia, E. Dalessandro, C. Lardo +14
In our HST photometric survey, we have been searching for multiple stellar populations (MPs) in Magellanic Clouds (MCs) massive star clusters which span a significant range of ages…
