    Herschel-ATLAS: Evolution of the 250 µm luminosity function out to z = 0.5
    We have determined the luminosity function of 250 μm-selected galaxies detected in the ~14 deg2 science demonstration region of the Herschel-ATLAS project out...

    High redshift galaxies in the ALHAMBRA survey. II. Strengthening the evidence of bright-end excess in UV luminosity functions at 2.5 ≤ z≤ 4.5 by PDF analysis
    Context. Knowing the exact shape of the ultraviolet (UV) luminosity function (LF) of high-redshift galaxies is important to understand the star formation...

    Hα luminosity function of H II regions: preliminary calibration of a powerful standard candle
    We propose the use of the H II region luminosity function (LF) as a refined powerful standard candle for extragalactic distances. We have found evidence of a...

    Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function
    The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These...

    Intergalactic Globular Clusters and the Faint End of the Galaxy Number Counts in A1656 (Coma)
    The existence of an intergalactic globular cluster population in the Coma cluster of galaxies has been tested using surface brightness fluctuations. The main...

    Is the initial mass function of low surface brightness galaxies dominated by low-mass stars?
    The rotation curves of low surface brightness (LSB) galaxies suggest that they possess significantly higher mass-to-light (M/L) ratios than their high surface...

    Keck HIRES spectra of the brown dwarf DENIS-P J1228.2-1547
    We report Keck high-resolution echelle spectroscopic observations of two very cool field dwarfs discovered by the near-IR photometric survey DENIS. DENIS-P...

    Luminosity and mass functions of the three main sequences of the globular cluster NGC 2808
    High-precision HST photometry has revealed that the globular cluster (GC) NGC 2808 hosts a triple main sequence (MS) corresponding to three stellar populations...
