    On the non-evolution of the dependence of black hole masses on bolometric luminosities for QSOs
    There are extremely luminous quasi stellar objects (QSOs) at high redshift which are absent at low redshift. The lower luminosities at low redshifts can be...

    On the post-common-envelope central star of the planetary nebula NGC 2346
    The common-envelope phase is one of the most poorly understood phases of (binary) stellar evolution, in spite of its importance in the formation of a wide range...

    On the Presence of Metallofullerenes in Fullerene-rich Circumstellar Envelopes
    The presence of neutral C 60 fullerenes in circumstellar environments has been firmly established by astronomical observations as well as laboratory experiments...

    On the radial abundance gradients of nitrogen and oxygen in the inner Galactic disc
    We present optical spectra of nine Galactic H II regions observed with the 10.4 m Gran Telescopio Canarias telescope and located at Galactocentric distances (R...

    On the Radial Distribution of Horizontal Branch Stars in NGC 2808
    We present accurate new ultraviolet and optical BVI photometry for the Galactic globular cluster NGC 2808 based on both ground-based and archival Hubble Space...

    On the Radial Extent of the Dwarf Irregular Galaxy IC10
    We present new deep and accurate space (Advanced Camera for Surveys-Wide Field Planetary Camera 2 on board the Hubble Space Telescope) and ground-based (Suprime...

    On the Radical Anion Spectra of Fullerenes C-60 and C-70
    The radical anion spectra of C-60 and C-70 can be easily generated and studied in primary aliphatic amines. In these conditions the C-60-center dot and C-70...

    On the Relative Distances of ω Centauri and 47 Tucanae
    We present precise optical and near-infrared ground-based photometry of two globular clusters (GCs): ω Cen and 47 Tuc. These photometric catalogs are unbiased...

    On the RR Lyrae Stars in Globulars. V. The Complete Near-infrared (JHK s ) Census of ω Centauri RR Lyrae Variables
    We present a new complete near-infrared (NIR, JHK s ) census of RR Lyrae stars (RRLs) in the globular ω Cen (NGC 5139). We collected 15,472 JHK s images with 4...
