Stellar metallicity gradients in the outer regions of galaxies are a critical tool for disentangling the contributions of in-situ and ex-situ formed stars. In the two-phase galaxy formation scenario, the initial gas collapse creates steep metallicity gradients, while the accretion of stars formed in satellites tends to flatten these gradients in the outskirts, particularly for massive galaxies. This work presents the first compilation of extended metallicity profiles over a wide range of galaxy… 
Radially extended metallicity profiles in nearby early-type galaxies
Stellar metallicity gradients in the outer regions of galaxies are a critical tool for disentangling the contributions of stars formed locally and stars accreted from external systems. The
The SLUGGS survey: Combining stellar and globular cluster metallicities in the outer regions of early-type galaxies
The outer halo regions of early-type galaxies carry key information about their past accretion history. However, spectroscopically probing the stellar component at such galactocentric radii is still
The origin of metallicity gradients in massive galaxies at large radii
Abstract We investigate the origin of stellar metallicity gradients in massive galaxies at large radii (r > 2 Reff) using ten cosmological zoom simulations of halos with 6 × 1012M⊙ < Mhalo < 2 ×
Timing the formation and assembly of early-type galaxies via spatially resolved stellar populations analysis
To investigate star formation and assembly processes of massive galaxies, we present here a spatially-resolved stellar populations analysis of a sample of 45 elliptical galaxies (Es) selected from

Abstract We investigate the differential impact of physical mechanisms, mergers and internal energetic phenomena, on the evolution of stellar metallicity gradients in massive, present-day galaxies
The SLUGGS Survey: stellar kinematics, kinemetry and trends at large radii in 25 early-type galaxies
Due to longer dynamical time-scales, the outskirts of early-type galaxies retain the footprint of their formation and assembly. Under the popular two-phase galaxy formation scenario, an initial in

The SLUGGS survey: Using extended stellar kinematics to disentangle the formation histories of low-mass S0 galaxies
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 GalaxieS (SLUGGS) survey.
The SLUGGS survey: combining stars, globular clusters, and planetary nebulae to understand the assembly history of early-type galaxies from their large radii kinematics
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

Abstract 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. Using the
