    GLACE survey: Galaxy activity in ZwCl0024+1652 cluster from strong optical emission lines
    Although ZwCl0024+1652 galaxy cluster at z ∼ 0.4 has been thoroughly analysed, it lacks a comprehensive study of star formation and nuclear activity of its...

    GLACE survey: OSIRIS/GTC tuneable filter Hα imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z = 0.395. I. Survey presentation, TF data reduction techniques, and catalogue
    The cores of clusters at 0 ≲ z ≲ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters...

    GLACE survey: OSIRIS/GTC tuneable imaging of the galaxy cluster ZwCl 0024.0+1652. II. The mass-metallicity relationship and the effect of the environment
    Aims: In this paper, we revisit the data for the galaxy cluster ZwCl 0024.0+1652 provided by the GLACE survey and study the mass-metallicity function and its...

    Global correlations between the radio continuum, infrared, and CO emissions in dwarf galaxies
    Correlations between the radio continuum, infrared, and CO emissions are known to exist for several types of galaxies and across several orders of magnitude...

    Global morphology and physical relations between the stars, gas and dust in the disc and arms of M100.
    We study star formation processes in the disc of the weakly barred grand design spiral galaxy M100 (NGC 4321) from a variety of images tracing recent massive...

    Global properties of the population of HII regions in NGC 7479 from photometric Hα imaging
    We present a new high quality continuum-subtracted Hα image of NGC 7479. Using a novel semi-automated technique we have determined the positions, angular sizes...

    Globular Cluster and Galaxy Formation: M31, the Milky Way, and Implications for Globular Cluster Systems of Spiral Galaxies
    We find that the globular cluster (GC) systems of the Milky Way and of our neighboring spiral galaxy, M31, comprise two distinct entities, differing in three...

    Globular cluster ejection, infall, and the host dark matter halo of the Pegasus dwarf galaxy
    Recent photometric observations revealed a massive, extended (M GC ≳ 10 5 M ☉; R h ̃ 14 pc) globular cluster (GC) in the central region (D 3D ≲ 100 pc) of the...
