    Discovery of new nearby L and late-M dwarfs at low Galactic latitude from the DENIS data base
    We report on new nearby L and late-M dwarfs (dphot = 3.0, later than M8.0) at low Galactic latitude (|b| 15°) over 4800 deg2 in the Deep Near Infrared Survey...

    Diverging UV and Hα fluxes of star-forming galaxies predicted by the IGIMF theory
    Although the stellar initial mass function (IMF) has only been directly determined in star clusters, it has been manifoldly applied on galaxy-wide scales. But...

    Environment of the Submillimeter-bright Massive Starburst HFLS3 at z ~ 6.34
    We describe the search for Lyman break galaxies (LBGs) near the submillimeter-bright starburst galaxy HFLS3 at z = 6.34 and a study on the environment of this...

    Environmental effects on the bright end of the galaxy luminosity function in galaxy clusters
    Context. The dependence of the luminosity function (LF) of cluster galaxies on the evolutionary state of the parent cluster is still an open question, in...

    Evidence for a fundamental stellar upper mass limit from clustered star formation
    The observed masses of the most massive stars do not surpass about 150 Msolar. This may either be a fundamental upper mass limit which is defined by the physics...

    Evolutionary paths among different red galaxy types at 0.3 < z < 1.5 and the late buildup of massive E-S0s through major mergers
    Some recent observations seem to disagree with hierarchical theories of galaxy formation about the role played by major mergers in the late buildup of massive E...

    Exploring the lower mass function in the young open cluster IC 4665
    We present a study of the young (30-100 Myr) open cluster IC 4665 with the aim to determine the shape of the mass function well into the brown dwarf regime. We...

    Exploring the planetary-mass population in the Upper Scorpius association
    We aim at identifying very low-mass isolated planetary-mass member candidates in the nearest OB association to the Sun, Upper Scorpius (USco) (145 pc; 5-10 Myr)...
