    The Filling Factor-Radius Relation for 58 H II Regions across the Disk of NGC 6946
    Using the OSIRIS tunable narrowband imager on the 10.4 m GTC (La Palma), we have mapped the SAB(rs)cd galaxy NGC 6946 over a ~7.3 × 7.5 arcmin2 field in the...

    The first Frontier Fields cluster: 4.5 μm excess in a z ~ 8 galaxy candidate in Abell 2744
    Aims: We present in this letter the first analysis of a z ~ 8 galaxy candidate found in the Hubble and Spitzer imaging data of Abell 2744 as part of the Hubble...

    The Formation of Molecular Clouds and Massive Stars
    In this talk I consider two questions. First, I investigate the formation of molecular clouds from diffuse interstellar gas. It has been argued that the...

    The formation of super-star clusters in disk and dwarf galaxies
    Super-star clusters are probably the largest star-forming entities in our local Universe, containing hundreds of thousands to millions of young stars usually...

    The Fornax3D project: Environmental effects on the assembly of dynamically cold disks in Fornax cluster galaxies
    We apply a population-orbit superposition metho1d to 16 galaxies in the Fornax cluster observed with MUSE/VLT in the context of the Fornax3D project. By fitting...

    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...
