    MIUSCAT: extended MILES spectral coverage - II. Constraints from optical photometry
    In this work, we show a comprehensive comparison of our new stellar population synthesis (SPS) MIUSCAT models with photometric data of globular clusters (GCs)...

    Mixed early and late-type properties in the bar of NGC 6221: Evidence for evolution along the Hubble sequence?
    Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (PA =5(deg) , 50...

    Mock observations with the Millennium Simulation: cosmological downsizing and intermediate-redshift observations
    Only by incorporating various forms of feedback can theories of galaxy formation reproduce the present-day luminosity function of galaxies. It has also been...

    Model Color-Magnitude Diagrams for Hubble Space Telescope Observations of Local Group Dwarf Galaxies
    In this Letter, we discuss a method to conduct a quantitative study of the star formation history (SFH) of Local Group (LG) galaxies using Hubble Space...

    Modeling of the HerMES Submillimeter Source Lensed by a Dark Matter Dominated Foreground Group of Galaxies
    We present the results of a gravitational lensing analysis of the bright z s = 2.957 submillimeter galaxy (SMG) HERMES found in the Herschel/SPIRE science...

    Modeling the ionizing spectra of H II regions: individual stars versus stellar ensembles
    Aims: We study how IMF sampling affects the ionizing flux and emission line spectra of low mass stellar clusters. Methods: We performed 2 × 106 Monte Carlo...

    Modeling the Stellar Populations in the Canis Major Overdensity: The Relation between the Old and Young Populations
    We analyze the stellar populations of the Canis Major stellar overdensity using quantitative color-magnitude diagram (CMD) fitting techniques. The analysis is...
