The WAGGS project -- III. Discrepant mass-to-light ratios of Galactic globular clusters at high metallicity
H. Dalgleish, S. Kamann, C. Usher +10
Observed mass-to-light ratios (M/L) of metal-rich globular clusters (GCs) disagree with theoretical predictions. This discrepancy is of fundamental importance since stellar populat…
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…
The WAGGS project - II. The reliability of the calcium triplet as a metallicity indicator in integrated stellar light
Christopher Usher, Thomas Beckwith, Sabine Bellstedt +12
Using data from the WiFeS Atlas of Galactic Globular cluster Spectra we study the behaviour of the calcium triplet (CaT), a popular metallicity indicator in extragalactic stellar p…
