    From the blue cloud to the red sequence (and over the green valley): investigating the evolution of galaxies over cosmological timescales
    In the local universe, galaxies fall into one of two populations: a star-forming blue cloud and a red sequence lacking star formation. At redshift z ~ 1.5...

    Galaxy environments at low- and high-z & Constraining the dust content of tadpoles
    One of the important questions in extragalactic astronomy concerns the debate between nature and nurture scenarios. Are the observed galaxy local properties the...

    Galaxy properties as a fingerprint of cosmology & fundamental physics
    Any viable theory of the formation and evolution of galaxies should be able to broadly account for the emergent properties of the galaxy population, and their...

    Globular cluster systems and the origin of early-type dwarfs in Virgo
    Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or recent end-products of the...

    Globular clusters systems and their host dark matter halos
    In the Λ-CDM galaxy formation paradigm, the star formation history of a galaxy is coupled to the total mass of its dark matter halo through processes like...

    Historical Perspectives on the Concept of Galaxy Size
    A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...

    How simple are galaxies?
    Galaxies are arguably complex systems. However, they also display many scaling relations between their physical properties, hinting that it might be possible to...

    Hunting for VIPERS red nuggets - traces of the past
    Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...
