  • Stellar Velocity Profiles and Line-Strengths out to Four Effective Radii in the Early-Type Galaxy NGC 3379
    We describe a new technique to measure stellar kinematics and line-strengths at large radii in nearby galaxies. Using the integral-field spectrograph SAURON as a ‘photon-collector’, we obtain spectra out to four effective radii (Re) in the early-type galaxy NGC 3379. By fitting orbit-based models to the extracted stellar velocity profile, we find

  • Steps toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XIII. Ultraviolet Observations of the Broad-Line Radio Galaxy 3C 390.3
    As part of an extensive multiwavelength monitoring campaign, the International Ultraviolet Explorer satellite was used to observe the broad-line radio galaxy 3C 390.3 during the period 1994 December 31-1996 March 5. Spectra were obtained every 6-10 days. The UV continuum varied by a factor of 7 through the campaign, while the broad emission lines

  • Strategies for AGN characterisation in the OTELO survey
    We present the current status of definition of the observational and analysis strategies for the study of Active Galactic Nuclei (AGN) in the OTELO survey. The main goal of this project is to determine the fraction of each species of AGN and their luminosity functions.

  • Stray Light Shielding for Formation Flying X-ray Telescopes
    Recent planning for Constellation-X has driven the exploration of grazing incidence telescopes with focal lengths of 50 m or greater. Formation flying, wherein separate optic and detector spacecraft travel in formation, is one approach to implementing such long focal lengths. This approach eliminates the telescope tube that is an integral part of

  • Strömgren Photometry of Galactic Globular Clusters. II. Metallicity Distribution of Red Giants in ω Centauri
    We present new intermediate-band Strömgren photometry based on more than 300 u, v, b, y images of the Galactic globular cluster ω Cen. Optical data were supplemented with new multiband near-infrared (NIR) photometry (350 J, H, Ks images). The final optical-NIR catalog covers a region of more than 20 × 20 arcmin squared across the cluster center. We

  • Strong Chromatic Microlensing in HE0047–1756 and SDSS1155+6346
    We use spectra of the double-lensed quasars HE0047–1756 and SDSS1155+6346 to study their unresolved structure through the impact of microlensing. There is no significant evidence of microlensing in the emission line profiles except for the Lyα line of SDSS1155+6346, which shows strong differences in the shapes for images A and B. However, the
