    Colours and luminosities of z = 0.1 galaxies in the EAGLE simulation
    We calculate the colours and luminosities of redshift z = 0.1 galaxies from the EAGLE simulation suite using the GALAXEV population synthesis models. We take...

    Constraining the top-light initial mass function in the extended ultraviolet disk of M 83
    Context. The universality or non-universality of the initial mass function (IMF) has significant implications for determining star formation rates and star...

    Converting Hα Luminosities into Star Formation Rates
    Star formation rates (SFRs) of galaxies are commonly calculated by converting the measured Hα luminosities (LHα) into current SFRs. This conversion is based on...

    Deep CCD photometry and the initial mass function of the core of the OB cluster Berkeley 86.
    Based on photometry of deep CCD frames of the central region of the OB cluster Berkeley 86, we derive the cluster mass function. The absence of current star...

    Deep spectroscopic luminosity function of Abell 85: no evidence for a steep upturn of the faint-end slope
    We present a new deep determination of the spectroscopic luminosity function (LF) within the virial radius of the nearby and massive Abell 85 (A85) cluster down...

    Deep spectroscopy of nearby galaxy clusters - I. Spectroscopic luminosity function of Abell 85
    We present a new deep spectroscopic catalogue for Abell 85, within 3.0 × 2.6 Mpc2 and down to Mr ˜ Mr^{ast } +6. Using the Visible Multi-Object Spectrograph at...

    Deep spectroscopy of nearby galaxy clusters - II. The Hercules cluster
    We carried out the deep spectroscopic observations of the nearby cluster A 2151 with AF2/WYFFOS@WHT. The caustic technique enables us to identify 360 members...

    Differences and similarities of stellar populations in LAEs and LBGs at z ∼ 3.4-6.8
    Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) represent the most common groups of star-forming galaxies at high z, and the differences between...

    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...
