    The Fornax3D project: intrinsic correlations between orbital properties and the stellar initial mass function
    Variations of the stellar initial mass function (IMF) in external galaxies have been inferred from a variety of independent probes. Yet the physical conditions...

    The Fundamental Metallicity Relation Emerges from the Local Anti-correlation between Star Formation Rate and Gas-phase Metallicity that Exists in Disk Galaxies
    The fundamental metallicity relation (FMR) states that galaxies of the same stellar mass but larger star formation rate (SFR) tend to have smaller gas-phase...

    The G-dwarf problem - A tentative analytical approach, relaxing instantaneous recycling
    The general solution for the birth function B(m,t) of stars, derived by Casuso et al. (1989) was used to obtain a first-order analytical approximation to this...

    The GaLAxy Cluster Evolution Survey (GLACE): overview and status report
    Aimed at understanding the evolution of galaxies in clusters, the GLACE survey is mapping a set of key optical lines in several galaxy clusters at z~0.40, 0.63...

    The galaxy-wide initial mass function of dwarf late-type to massive early-type galaxies
    Observational studies are showing that the galaxy-wide stellar initial mass function (IMF) is top-heavy in galaxies with high star formation rates (SFRs)...

    The GALEX/S4G Surface Brightness and Color Profiles Catalog. I. Surface Photometry and Color Gradients of Galaxies
    We present new spatially resolved surface photometry in the far-ultraviolet (FUV) and near-ultraviolet (NUV) from images obtained by the Galaxy Evolution...

    The GALEX/S4G UV–IR Color–Color Diagram: Catching Spiral Galaxies Away from the Blue Sequence
    We obtained GALEX FUV, NUV, and Spitzer/IRAC 3.6 μm photometry for \gt 2000 galaxies, available for 90% of the S4G sample. We find a very tight GALEX blue...

    The Globular Cluster Relative Ages and the Milky Way Formation Time Scale
    The ACS Survey of Galactic Globular Clusters is a Hubble Space Telescope (HST) Treasury program designed to provide a new large, deep and homogeneous...

    The huge (but forgotten) population of weak line galaxies in the SDSS: AGN or just retired galaxies
    This talk is divided into two related parts. First, we will call your attention to a basic, but often overlooked worrying fact, and presents ways of dealing...
