    Prospects for high-z cluster detections with Planck, based on a follow-up of 28 candidates using MegaCam at CFHT
    The Planck catalogue of SZ sources limits itself to a significance threshold of 4.5 to ensure a low contamination rate by false cluster candidates. This means...

    Pseudobulges in the Disk Galaxies NGC 7690 and NGC 4593
    We present Ks-band surface photometry of NGC 7690 (Hubble type Sab) and NGC 4593 (SBb). We find that, in both galaxies, a major part of the ``bulge'' is as flat...

    Pursuing Local Group blue massive stars with WSO-ISSIS
    The Local Group galaxies enable us to study the impact of metallicity on the structure and evolution of massive stars through spectroscopic analyses. However...

    Quantifying high z galaxy selection and visibility with the COSMOPACK tool
    We have developed COSMOPACK, a set of tools that transform images of real galaxies to depict their appearance at a given redshift as observed with a given...

    Quantitative Morphological Analysis of Galaxies at Intermediate Red Shift: Clues to Galaxy Evolution
    We have developed morphological analysis software for studying galaxies from low to high redshifts. This code is designed to extract quantitative information...

    Quantitative morphological analysis of the Hubble Deep Field North and Hubble Deep Field South - I. Early- and late-type luminosity-size relations of galaxies out to z~ 1
    Based on drizzled F606W and F814W images, we present quantitative structural parameters in the V-band rest-frame for all galaxies with z 1 and I814(AB) 24.5...

    Quantitative Morphology of Galaxies in the Core of the Coma Cluster
    We present a quantitative morphological analysis of 187 galaxies in a region covering the central 0.28 deg2 of the Coma Cluster. Structural parameters from the...
