The discovery of a microarcsecond quasar: J1819+3845
J. Dennett-Thorpe, A. G. de Bruyn
We report on the discovery of a source which exhibits over 300% amplitude changes in radio flux density on the period of hours. This source, J1819+3845, is the most extremely varia…
The radio source B 1834+620: A double-double radio galaxy with interesting properties
Arno P. Schoenmakers, A. G. de Bruyn, H. J. A. Rottgering +1
We present a study of the peculiar radio galaxy B 1834+620. It is characterised by the presence of a 420-kpc large edge-brightened radio source which is situated within, and well a…
Radio galaxies with a `double-double' morphology: I - Analysis of the radio properties and evidence for interrupted activity in active galactic nuclei
Arno P. Schoenmakers, A. G. de Bruyn, H. J. A. Rottgering +2
We present four Mpc-sized radio galaxies which consist of a pair of double-lobed radio sources, aligned along the same axis, and with a coinciding radio core. We have called these…
CLASS B1152+199 and B1359+154: Two New Gravitational Lens Systems Discovered in the Cosmic Lens All-Sky Survey
S. T. Myers, D. Rusin, C. D. Fassnacht +9
The third phase of the Cosmic Lens All-Sky Survey (CLASS) has recently been completed, bringing the total number of sources imaged to over 15000 in the CLASS and JVAS combined surv…
HI and OH absorption at z=0.89
Jayaram N. Chengalur, A. G. de Bruyn, D. Narasimha
We report on WSRT observations of HI and OH absorption at z=0.885 towards the radio lens PKS 1830-21, mm wave transitions of several molecular species have already been observed at…
Measuring Cosmological Parameters with the JVAS and CLASS Gravitational Lens Surveys
P. Helbig, R. D. Blandford, I. W. A. Browne +11
The JVAS (Jodrell Bank-VLA Astrometric Survey) and CLASS (Cosmic Lens All-Sky Survey) are well-defined surveys containing about ten thousand flat-spectrum radio sources. For many r…
Optical spectroscopy of faint gigahertz peaked spectrum sources
I. A. G. Snellen, R. T. Schilizzi, M. N. Bremer +3
We present spectroscopic observations of a sample of faint Gigahertz Peaked Spectrum (GPS) radio sources drawn from the Westerbork Northern Sky Survey (WENSS). Redshifts have been…
