    A significant contribution to the cosmic X-ray background from sources associated with nearby galaxies

    THE origin of the cosmic X-ray background remains a mystery after thirty years of study. The three properties of the background radiation commonly used for tackling this problem—its spectrum, isotropy and reso...

    The galactic ridge observed by Exosat

    We have used Exosat to map the distribution of X-ray emission in the galactic plane. In addition to numerous point sources, the map reveals a narrow continuous ridge of emission which extends along the galacti...

    On the detection of large-scale inhomogeneities in the Universe

    THE detection of large-scale inhomogeneities in the Universe has proceeded along a number of fronts. The observed spatial distribution of galaxies indicates clum** of matter on length scales up to ∼30 Mpc (r...

    Statistical investigation of compact emitting regions in extragalactic radio sources

    EXTRAGALACTIC radio sources of high total luminosity usually contain compact emitting regions. These may be coincident with the optical galaxy or quasar, or they may be situated at the outer edges of extended ...

    Radio structure of the ‘double quasar’ 4C11.50

    WAMPLER et al.1 have recently announced the discovery of a close pair of optical quasars associated with the radio source 4C11.50. The brighter quasar (a) has a redshift of 0.436, whereas its companion (b), 4.8 a...

    Angular Diameters of Quasars of Unusual Colour

    TWO neutral-coloured stellar objects, OH471 and OQ172, have been shown to be QSOs with redshifts of 3.40 and 3.53 respectively1,2. This has stimulated interest in other radio sources identified with stellar objec...
