    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...
  • Publication
    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...
  • Talk
    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...

    The infrared-radio correlation of star-forming galaxies is strongly M<SUB>⋆</SUB>-dependent but nearly redshift-invariant since z ∼ 4
    Over the past decade, several works have used the ratio between total (rest 8‒1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (q...

    The interacting system NGC 7753-7752 (Arp 86). I - BVRI photometry
    BVRI surface photometry is presented for the interacting galaxy pair Arp 86 (NGC 7753-7752). Deep high-resolution images were obtained in order to study the...

    The Interstellar Medium in High-redshift Submillimeter Galaxies as Probed by Infrared Spectroscopy*
    Submillimeter galaxies (SMGs) at z≳ 1 are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year...
