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…

The SLUGGS Survey: A comparison of total-mass profiles of early-type galaxies from observations and cosmological simulations, to 4 effective radii
Sabine Bellstedt, Duncan A. Forbes, Aaron J. Romanowsky +11
We apply the Jeans Anisotropic MGE (JAM) dynamical modelling method to SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey data of early-type galaxies in the stellar mass…

The WAGGS project - I. The WiFeS Atlas of Galactic Globular cluster Spectra
Christopher Usher, Nicola Pastorello, Sabine Bellstedt +9
We present the WiFeS Atlas of Galactic Globular cluster Spectra, a library of integrated spectra of Milky Way and Local Group globular clusters. We used the WiFeS integral field sp…
