    A near infrared speckle imaging study of T Tauri Stars

    The results of a speckle imaging survey of T Tauri stars suggest that most, if not all, young low mass stars have companions. Repeated observations of these young binary stars have revealed orbital motion in t...

    Near- and Mid-IR Imaging of the Nuclear Starburst in NGC 3079

    The nearly edge-on Sc galaxy NGC 3079 displays strong nuclear optical emission lines of Ha, Hβ, [NII], [SII], [OI] and [OIII], and has been classified as a LINER based on the widths and relative fluxes of these l...

    Near-Infrared Imaging of Ultraluminous IRAS Galaxies

    IRAS discovered a class of objects which emit most of their radiation at infrared wavelengths and which possess bolometric luminosities comparable to those of classical quasars. Due to their extreme power, and...

    Millimeter Observations of Luminous IRAS Galaxies

    We have observed a group of luminous IRAS galaxies in the continuum at 1.25mm with the Caltech Submillimeter Observatory in 1988 May and September. Table I lists the galaxies and their measured flux densities ...

    IRAS Observations of Active Galaxies

    The IRAS survey gives an unbiased view of the infrared properties of the active galaxies. Seyfert galaxies occupy much the same area in color-color plots as do normal infrared bright galaxies, but extend the r...

    Zu axialsymmetrischen stationären Lösungen der Einsteinschen Feldgleichungen für das Vakuum

    For axialsymmetric stationary vacuum fields Einstein equations reduce to a system, derivable from a simple Lagrangian. An investigation of its forminvariance leads to a method to construct from known solutions...
