    The Initial Mass Function of Lens Galaxies from Quasar Microlensing
    We present a new approach to studying the initial mass function (IMF) in external galaxies based on quasar microlensing observations. We use measurements of...

    The Isaac Newton Telescope Monitoring Survey of Local Group Dwarf Galaxies. I. Survey Overview and First Results for Andromeda I
    An optical monitoring survey in nearby dwarf galaxies was carried out with the 2.5 m Isaac Newton Telescope. Fifty-five dwarf galaxies and four isolated...

    The luminosity function evolution of soft X-ray-selected active galactic nuclei in the RIXOS survey
    A sample of 198 soft X-ray-selected active galactic nuclei (AGN) from the ROSAT International X-ray Optical Survey (RIXOS) is used to investigate the X-ray...

    The luminosity function of stars in the intermediate age open cluster NGC 7789
    We report the results of a CCD investigation of stars in a selected region near the center of the intermediate age galactic cluster NGC 7789. A CM diagram is...

    The luminosity of cluster galaxies in the Cluster-EAGLE simulations
    We computed the luminosity of simulated galaxies of the C-EAGLE project, a suite of 30 high-resolution zoom-in simulations of galaxy clusters based on the EAGLE...

    The magnitude difference between the main sequence turn off and the red giant branch bump in Galactic globular clusters
    We present new measurements of the magnitude of the main sequence turn off and the red giant branch bump in the luminosity function of a sample of Galactic...

    The mass function of IC 4665 revisited by the UKIDSS Galactic Clusters Survey
    Context. Knowledge of the mass function in open clusters constitutes one way to constrain the formation of low-mass stars and brown dwarfs as does the knowledge...

    The maximum stellar mass, star-cluster formation and composite stellar populations
    We demonstrate that the mass of the most massive star in a cluster correlates non-trivially with the cluster mass. A simple algorithm, according to which a...

    The mmax-Mecl relation, the IMF and IGIMF: probabilistically sampled functions
    We introduce a new method to measure the dispersion of mmax values of star clusters and show that the observed sample of mmax is inconsistent with random...
