We construct a suite of discrete chemo-dynamical models of the giant elliptical galaxy NGC 5846. These models are a powerful tool to constrain both the mass distribution and intern…
The SLUGGS survey: a new mask design to reconstruct the stellar populations and kinematics of both inner and outer galaxy regions
Nicola Pastorello, Duncan A. Forbes, Adriano Poci +7
Integral field unit spectrographs allow the 2D exploration of the kinematics and stellar populations of galaxies, although they are generally restricted to small fields-of-view. Us…

We report the discovery of a complex extended density enhancement in the Globular Clusters (GCs) in the central ( Mpc) of the Fornax cluster,…
An overmassive Dark Halo around an Ultra-diffuse Galaxy in the Virgo Cluster
Michael A. Beasley, Aaron J. Romanowsky, Vincenzo Pota +4
Ultra diffuse galaxies (UDGs) have the sizes of giant galaxies but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but their low sur…

[Abrigded] We have started a new deep, multi-imaging survey of the Fornax cluster, dubbed Fornax Deep Survey (FDS), at the VLT Survey Telescope. In this paper we present the deep p…
The SLUGGS Survey: globular clusters and the dark matter content of early-type galaxies
Duncan A. Forbes, Adebusola Alabi, Aaron J. Romanowsky +4
A strong correlation exists between the total mass of a globular cluster (GC) system and the virial halo mass of the host galaxy. However, the total halo mass in this correlation i…
The SLUGGS Survey: The Assembly Histories of Individual Early-type Galaxies
Duncan A. Forbes, Aaron J. Romanowsky, Nicola Pastorello +5
Early-type (E and S0) galaxies may have assembled via a variety of different evolutionary pathways. Here we investigate these pathways by comparing the stellar kinematic properties…
The SLUGGS Survey: stellar kinematics, kinemetry and trends at large radii in 25 early-type galaxies
Caroline Foster, Nicola Pastorello, Joel Roediger +9
Due to longer dynamical timescales, the outskirts of early-type galaxies retain the footprint of their formation and assembly. Under the popular two-phase galaxy formation scenario…
