    Baryon acoustic oscillations from Integrated Neutral Gas Observations: Broadband corrugated horn construction and testing

    The Baryon acoustic oscillations from Integrated Neutral Gas Observations (BINGO) telescope is a 40-m class radio telescope under construction that has been designed to measure the large-angular-scale intensit...

    Spectral differences between radio galaxies and quasars

    IT has been suggested recently1–4 that two classes of radio-loud extragalactic object, narrow-line radio galaxies and quasars, are intrinsically similar, differing only in the angle from which they are seen by th...

    Anisotropic optical and X-ray emission in quasars

    IT is of fundamental importance in the study of quasars to understand whether or not their continuum emission is isotropic, because this affects the overall energy budget and can also help to distinguish betwe...

    MERLIN observations of superluminal radio sources

    Powerful extragalactic radio sources may all be members of a single family in which those showing superluminal behaviour are the ones in which a relativistic jet is directed towards the observer. The superlumi...

    VLBI structures of the images of the double QSO 0957 + 561

    Very long baseline interferometry (VLBI) observations of the double QSO 0957 + 561 have revealed radio fine structure in the two ‘image’ components A and B. The structures are similar, both of the ‘core–jet’ t...

    VLBI Observations of the double QSO, 0957 + 561 A, B

    Walsh et al.1 originally suggested that the double QSO 0957 + 561 A, B might be images of the same object formed by a gravitational lens because of their remarkably similar optical spectra. Additional optical spe...

    Radio studies of the double QSO, 0957 + 561A, B

    The radio source 0957 + 561 has at least four components. Two coincide with the optical QSOs, which is in accordance with the hypothesis that the QSOs are images of a single object due to a gravitational lens....

    Transient radio source near the galactic centre

    A VARIETY of interesting objects have been discovered in recent years within several arc min of the galactic centre. These include the main (east and west)1 components of the radio source Sgr A, a compact radio s...

    QSOs of high red shift?

    WE have completed a series of observations at Jodrell Bank on the radio structures of a complete sample of QSO candidates identified from the Parkes ±4° equatorial survey. Four sources are of particular intere...

    Physical Sciences: Some Identifications of Radio Sources with Neutral Stellar Objects

    WE present twenty-four identifications of radio sources with neutral coloured objects of stellar appearance. We consider these objects to be of special interest because they do not fall into the two normally 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...

    Two Bright New Quasi-stellar Radio Sources

    A 2,695 MHz survey of radio sources in a narrow strip of declination has recently been completed with the Jodrell Bank Mk II radio telescope (full details will be published later). Accurate positions for all t...
