    The S4G Perspective on Circumstellar Dust Extinction of Asymptotic Giant Branch Stars in M100
    We examine the effect of circumstellar dust extinction on the near-IR (NIR) contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters...

    The Sagittarius dwarf irregular galaxy (SagDIG): distance and star formation history
    The distance, star formation history and global properties of the Local Group dIrr galaxy SagDIG are derived based on an [I-(V-I)] colour-magnitude diagram of ~...

    The SAMI galaxy survey: stellar population radial gradients in early-type galaxies
    We study the internal radial gradients of the stellar populations in a sample comprising 522 early-type galaxies (ETGs) from the SAMI (Sydney-AAO Multi-object...

    The SAMI Galaxy Survey: the third and final data release
    We have entered a new era where integral-field spectroscopic surveys of galaxies are sufficiently large to adequately sample large-scale structure over a...

    The SAMI-Fornax Dwarfs Survey - II. The Stellar Mass Fundamental Plane and the dark matter fraction of dwarf galaxies
    We explore the kinematic scaling relations of 38 dwarf galaxies in the Fornax Cluster using observations from the SAMI integral field spectrograph. We focus on...

    The SAMI-Fornax Dwarfs Survey - III. Evolution of [α/Fe] in dwarfs, from Galaxy Clusters to the Local Group
    Using very deep, high spectral resolution data from the SAMI Integral Field Spectrograph, we study the stellar population properties of a sample of dwarf...

    The SAMI-Fornax Dwarfs Survey - IV. Star formation histories of dwarf and early-type galaxies: insights from full spectral fitting
    We present a study on the star formation histories (SFHs) of galaxies covering the range 10 4 < M ⋆/M ⊙ < 10 12, leveraging full spectral fitting algorithms...

    The SAMI-Fornax Dwarfs Survey I: sample, observations, and the specific stellar angular momentum of dwarf elliptical galaxies
    Dwarf ellipticals are the most common galaxy type in cluster environments; however, the challenges associated with their observation mean that their formation...
  • Publication
    The SAURON project - IV. The mass-to-light ratio, the virial mass estimator and the Fundamental Plane of elliptical and lenticular galaxies
    We investigate the well-known correlations between the dynamical mass-to-light ratio (M/L) and other global observables of elliptical (E) and lenticular (S0)...
