    Broad absorption line quasars with redshifted troughs: high-velocity infall or rotationally dominated outflows?
    We report the discovery in the Sloan Digital Sky Survey (SDSS) and the SDSS-III Baryon Oscillation Spectroscopic Survey of 17 broad absorption line (BAL)...

    Broad band JHK infrared photometry of an extended sample of late type dwarfs and subdwarfs.
    The results of a long term programme of broad band JHK photometry, for a sample of 360 late type stars, made at the Observatorio del Teide (Tenerife, Spain) are...

    Broad Components in Optical Emission Lines from the Ultra-luminous X-ray Source NGC 5408 X-1
    High-resolution optical spectra of the ultra-luminous X-ray source (ULX) NGC 5408 X-1 show a broad component with a width of ~750 km s-1 in the He II and Hβ...
  • Publication
    Broad Emission Lines in Active Galaxies: Horns, Bumps and Shoulders
    have complex and highly structured profiles. We discuss, in the context of the discrete cloud model of the broad-line region, three possible mechanisms by which...

    Broad iron emission line and kilohertz quasi-periodic oscillations in the neutron star system 4U 1636-53
    Both the broad iron (Fe) line and the frequency of the kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low-mass X-ray binaries (LMXBs) can...
  • Publication
    Broad iron line in the fast spinning neutron-star system 4U 1636-53
    We analysed the X-ray spectra of six observations, simultaneously taken with XMM-Newton and Rossi X-ray Timing Explorer (RXTE), of the neutron-star low-mass X...

    Broad Low-Intensity Wings in the Emission-Line Profiles of Four Wolf-Rayet Galaxies
    High-resolution spectroscopic observations have been obtained for the Wolf-Rayet galaxies He 2-10, II Zw 40, POX 4, and Tol 35. Several subregions have been...

    Broad Relativistic Iron Emission Line Observed in SAX J1808.4-3658
    During the 2008 September-October outburst of the accreting millisecond pulsar SAX J1808.4-3658, the source was observed by both Suzaku and XMM-Newton...

    Broad-band continuum and line emission of the gamma-ray blazar PKS 0537-441
    PKS 0537-441, a bright gamma -ray emitting blazar, was observed at radio, optical, UV and X-ray frequencies during various EGRET pointings, often quasi...
