Radio and near-infrared observations of the steep spectrum Galactic plane radio source WKB 0314+57.8
Radio and near-infared observations towards the steep spectrum Galactic plane radio source WKB 0314+57.8 are presented, in order to clarify the nature of this source. The radio observations include archival and survey data, together with new Giant Metrewave Radio Telescope observations at 617 MHz. The near-infrared observations are in the J and K bands, from the Gemini instrument on the Shane 3...
متن کاملHST , radio and infrared observations of 28 3 CR radio galaxies at redshift z ∼ 1 — I . The observations
Hubble Space Telescope images are presented of a sample of 28 3CR radio galaxies with redshifts in the range 0.6 < z < 1.8, together with maps at comparable angular resolution of their radio structure, taken using the Very Large Array. Infrared images of the fields, taken with the United Kingdom InfraRed Telescope, are also presented. The optical images display a spectacular range of structures...
متن کاملOptical identifications of faint radio sources 1 1997
Deep imaging and spectroscopy have been carried out for optical counterparts of a sample of 68 faint radio sources (S > 0.2 mJy) in the “Marano Field”. About 60% of the sources have been optically identified on deep CCD exposures (limit R ' 24.0) or ESO 3.6–m plates (limit bJ ' 22.5). Thirty–four spectra (50% of the total radio sample) were obtained with the ESO 3.6–m telescope and 30 redshifts...
متن کاملLinking radio to infrared: a radio source count model
We investigate the populations and evolution of normal and active galaxies by extending the infrared source count model of Rowan-Robinson (2001) into the radio. The FIR-radio correlation is used to extend the SEDs to the radio region and it is assumed that there are two distinct populations of quasar: radio loud and radio quiet. It is found that the radio luminosity function and source count da...
متن کاملRadio , optical and infrared observations of CLASS B 0128 + 437
We present new observations of the gravitational lens system CLASS B0128+437 made in the optical, infrared and radio regimes. HubbleSpaceT elescope observations detect only a very faint, extended object in I-band with no obvious emission from the lensed images visible; no detection at all is made in V -band. The lens system is detected with much higher signal to noise with UKIRT in K-band and, ...
