  • Giant Radio Quasars properties

    We analysed the optical and radio properties of lobe-dominated giant-sized (>0.72Mpc) radio quasars and compared the results with those derived for a sample of smaller radio...
  • Compact Groups of galaxies from 2MASX

    We present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the Two-Micron All Sky Survey (2MASS) extended source catalogue. A total...
  • Structural parameters of M33 star clusters

    We present the morphological properties of 161 star clusters in M33 using the Advanced Camera for Surveys Wide Field Channel on-board the Hubble Space Telescope using...
  • ATLAS 5.5GHz survey of Chandra Deep Field South

    Star-forming galaxies are thought to dominate the sub-mJy radio population, but recent work has shown that low-luminosity active galactic nuclei (AGNs) can still make a...
  • Morphology of supernova host galaxies

    This paper presents an analysis of core-collapse supernova distributions in isolated and interacting host galaxies, paying close attention to the selection effects involved in...
  • Structure and dynamics of 8 low SB disc galaxies

    We present the radial profiles of the H{alpha}, Mg and Fe line-strength indices for a sample of eight spiral galaxies with a low-surface-brightness stellar disc and a bulge. The...
  • Sample of Compact Group (CG) galaxies

    We construct a sample of 75863 star-forming galaxies with robust metallicity and star formation rate (SFR) measurements from the Sloan Digital Sky Survey Data Release 7, from...
  • SDSS DR7 groups, clusters and filaments

    We have developed a multiscale structure identification algorithm for the detection of overdensities in galaxy data that identifies structures having radii within a user-defined...
  • Morphology of galaxies in WINGS clusters

    We present the morphological catalog of galaxies in nearby clusters of the WINGS survey (Fasano et al., 2006A&A...445..805F). The catalog contains a total number of 39923...
  • End of red sequence galaxies in Galaxy Zoo

    We present a study of local post-starburst galaxies (PSGs) using the photometric and spectroscopic observations from the Sloan Digital Sky Survey and the results from the Galaxy...
  • Morphology of luminous radio-loud AGN

    We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2Jy radio galaxies at intermediate redshifts (0.05<z<0.7) and...
  • VLBI observations of NRAO 530 at 22, 43 and 86GHz

    NRAO 530 is an optically violent variable source and has been studied with multi-epoch multifrequency high-resolution very long baseline interferometry (VLBI) observations. NRAO...
  • Compact groups of galaxies in SDSS DR7

    We investigate the properties of photometrically selected compact groups (CGs) in the Sloan Digital Sky Survey. In this paper, the fourth in a series, we focus on understanding...
  • SDSS red gal. automated morph. classification

    In the last decade, the advent of enormous galaxy surveys has motivated the development of automated morphological classification schemes to deal with large data volumes....
  • Stellar population trends in S0 galaxies

    We present stellar population age and metallicity trends for a sample of 59 S0 galaxies based on optical Sloan Digital Sky Survey (SDSS) and near-infrared (NIR) J and H...
  • Coma Treasury Survey. Structural parameters

    We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the Hubble Space Telescope/ACS Coma Treasury Survey. Parameters from Sersic fits to the...
  • Morphological types from Galaxy Zoo 1

    Morphology is a powerful indicator of a galaxy's dynamical and merger history. It is strongly correlated with many physical parameters, including mass, star formation history...
  • GHASP: H{alpha} data cubes for 153 galaxies

    Due to their large distances, high-redshift galaxies are observed at a very low spatial resolution. In order to disentangle the evolution of galaxy kinematics from...
  • Central galaxies in groups and clusters

    Using a statistically representative sample of 911 central galaxies (CENs) from the Sloan Digital Sky Survey (SDSS) Data Release 4 group catalogue, we study how the structure...
  • Fundamental Plane analysis in Shapley

    We present a Fundamental Plane (FP) analysis of 141 early-type galaxies in the Shapley supercluster at z=0.049 based on spectroscopy from the AAOmega spectrograph at the...
