    'Global mapping' B-band photometry of a complete sample of Fornax and Virgo early-type galaxies
    We present the B-band surface photometry of 19 early-type galaxies of the Virgo cluster, and of 28 galaxies of the same morphological type belonging to the...

    2MASS, SDSS and BVRI photometry for 825 stars (Bilir+, 2008)
    We present colour transformations for the conversion of the 2MASS photometric system to the Johnson-Cousins UBVRI system and further into the SDSS ugriz system...
  • Publication
    2MASS/SDSS data for 806 ultracool dwarfs (Zhang+, 2010)
    SDSS (II/294), 2MASS (II/246) and UKIDSS (II/304) photometry of 806 ultra-cool dwarfs. Proper motions are found by dividing the difference between the 2MASS and...

    8.6um imaging of 47 Tuc (Momany+, 2012)
    Our observations were obtained using the VLT spectrometer and imager for the MIR (VISIR) currently located at the Cassegrain focus of UT3. These observations...

    A Comparative Study of the Microvariability Properties in Radio-loud and Radio-quiet Quasars
    We have performed photometric optical observations of a sample of 17 core-dominated radio-loud quasars (CRLQs) and 17 radio-quiet quasars (RQQs). The aims were...

    A composite HII region luminosity function (Bradley+, 2006)
    HII region catalogues for 57 face on spiral galaxies within v

    A Correlation between Galaxy Light Concentration and Supermassive Black Hole Mass
    We present evidence for a strong correlation between the concentration of bulges and the mass of their central supermassive black hole (Mbh)-more concentrated...

    A Correlation between Light Concentration and Cluster Local Density for Elliptical Galaxies
    Using photometric and redshift data for the Virgo and Coma Clusters, we present evidence for a correlation between the light concentration of elliptical...
  • Publication
    A Correlation between Light Profile and [Mg/Fe] Abundance Ratio in Early-Type Galaxies
    We explore possible correlations between light profile shapes, as parameterized by the Sérsic index n or the concentration index Cre(1/3), and relevant stellar...
