Using new and archival data, we study the kinematic properties of the nearest field S0 galaxy, NGC 3115, out to $sim6.5$ half-light radii ($R_mathrm{e}$) from its stars (integrated starlight), globular clusters (GCs) and planetary nebulae (PNe). We find evidence of three kinematic regions with an inner transition at $sim0.2 R_mathrm{e}$ from a dispersion-dominated bulge ($V_mathrm{rot}/sigma <1$) to a fast-rotating disk ($V_mathrm{rot}/sigma >1$), and then an additional transition from the disk to a slowly rotating spheroid at $sim2-2.5, R_mathrm{e}$, as traced by the red GCs and PNe (and possibly by the blue GCs beyond $sim5, R_mathrm{e}$). From comparison with simulations, we propose an assembly history in which the original progenitor spiral galaxy undergoes a gas-rich minor merger that results in the embedded kinematically cold disk that we see today in NGC 3115. At a later stage, dwarf galaxies, in mini mergers (mass-ratio $<$ 1:10), were accreted building-up the outer slowly rotating spheroid, with the central disk kinematics largely unaltered. Additionally, we report new spectroscopic observations of a sample of ultra-compact dwarfs (UCDs) around NGC 3115 with the Keck/KCWI instrument. We find that five UCDs are inconsistent with the general rotation field of the GCs, suggesting an textit{ex-situ} origin for these objects, i.e. perhaps the remnants of tidally stripped dwarfs. A further seven UCDs follow the GC rotation pattern, suggesting an textit{in-situ} origin and, possibly a GC-like nature.
We observed twelve nearby HI -detected early-type galaxies (ETGs) of stellar mass $sim 10^{10}Modot leq M_* leq sim 10^{11}Modot$ with the Mitchell Integral-Field Spectrograph, reaching approximately three half-light radii in most cases. We extracted
We investigate the kinematic properties of nine nearby early-type galaxies with evidence of a disk-like component. Three of these galaxies are located in the field, five in the group and only one in the cluster environment. By combining the kinematic
Using the newly commissioned KCWI instrument on the Keck-II telescope, we analyse the stellar kinematics and stellar populations of the well-studied massive early-type galaxy (ETG) NGC 1407. We obtained high signal-to-noise integral-field-spectra for
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 internal dynamics of multiple tracer populations. We use Jeans models to sim
A detailed study of the morphology of lenticular galaxies is an important way to understand how this type of galaxy formed and evolves over time. Decomposing a galaxy into its components (disc, bulge, bar, ...) allows recovering the colour gradients
