    The Outer Disks of Early-Type Galaxies. I. Surface-Brightness Profiles of Barred Galaxies
    We present a study of 66 barred, early-type (S0-Sb) disk galaxies, focused on the disk surface brightness profile outside the bar region, with the aim of...

    The Outer Disks of Early-type Galaxies. II. Surface-brightness Profiles of Unbarred Galaxies and Trends with Hubble Type
    We present azimuthally averaged radial profiles of R-band surface brightness for a complete sample of 47 early-type, unbarred galaxies, as a complement to our...

    The outskirts of spiral galaxies: touching stellar halos at z˜0 and z˜1
    Taking advantage of ultra-deep imaging of SDSS Stripe82 and the Hubble Ultra Deep Field by HST, we explore the properties of stellar halos at two relevant...

    The oxygen abundance gradient in M 101: The reliability of the P method
    We present the oxygen abundance determination for 90 H II regions in the inner parts of the grand design galaxy M 101. The abundances were derived employing the...

    The Padova-Millennium Galaxy and Group Catalogue (PM2GC): the group-finding method and the PM2GC catalogues of group, binary and single field galaxies
    We present the construction and describe the properties of the Padova-Millennium Galaxy and Group Catalogue (PM2GC), a galaxy catalogue representative of the...

    The PAU Survey: Galaxy stellar population properties estimates with narrowband data
    A newfound interest has been seen in narrowband galaxy surveys as a promising method for achieving the necessary accuracy on the photometric redshift estimate...

    The PEP survey: clustering of infrared-selected galaxies and structure formation at z ˜ 2 in GOODS-South
    This paper presents the first direct estimate of the 3D clustering properties of far-infrared sources up to z˜ 3. This has been possible thanks to the PACS...

    The photocentre-AGN displacement: is M87 actually harbouring a displaced supermassive black hole?
    M87 has been identified as a displaced supermassive black hole (SMBH) candidate. We investigated this possibility by a temporal analysis of 12 adaptive-optics...
