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…
Evidence of a Bottom-heavy Initial Mass Function in Massive Early-type Galaxies from Near-infrared Metal Lines
David J. Lagattuta, Jeremy R. Mould, Duncan A. Forbes +3
We present new evidence for a variable stellar initial mass function (IMF) in massive early-type galaxies, using high-resolution, near-infrared spectroscopy from the Folded-port In…
The SLUGGS survey: Using extended stellar kinematics to disentangle the formation histories of low mass S0 galaxies
Sabine Bellstedt, Duncan A. Forbes, Caroline Foster +5
We utilise the DEIMOS instrument on the Keck telescope to measure the wide-field stellar kinematics of early-type galaxies as part of the SAGES Legacy Unifying Globulars and Galaxi…
The SLUGGS survey: Combining stellar and globular cluster metallicities in the outer regions of early-type galaxies
Nicola Pastorello, Duncan A. Forbes, Christopher Usher +9
The outer halo regions of early-type galaxies carry key information about their past accretion history. However, spectroscopically probing the stellar component at such galactocent…
Small scatter and nearly-isothermal mass profiles to four half-light radii from two-dimensional stellar dynamics of early-type galaxies
Michele Cappellari, Aaron J. Romanowsky, Jean P. Brodie +9
We study the total mass-density profile for a sample of 14 fast-rotator early-type galaxies (stellar masses ). We combine observations from the SLUGG…
A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
Vincenzo Pota, Jean P. Brodie, Terry Bridges +20
We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. Imaging of NGC 4649 was…
