    The structure models for galaxy clustering.
    The models for galaxy clustering in which galaxies are identified with peaks on the mass density field smoothed on an appropriate scale are plagued by some...

    The structure of galactic disks. Studying late-type spiral galaxies using SDSS
    Using imaging data from the SDSS survey, we present the g' and r' radial stellar light distribution of a complete sample of ~90 face-on to intermediate inclined...

    The structure of the interstellar gas towards stars in the globular cluster NGC 6541
    Observations are presented of high resolution interstellar Na I D and K I (lambda 7699 Angstroms) line profiles towards 7 stars in the globular cluster NGC 6541...

    The substellar mass function in the central region of the open cluster Praesepe from deep LBT observations
    Context. Studies of the mass function (MF) of open clusters of different ages allow us to probe the efficiency with which brown dwarfs evaporate from clusters...
