B2045+265: A New Four-Image Gravitational Lens from CLASS
C. D. Fassnacht, R. D. Blandford, J. G. Cohen +14
We have discovered a new gravitational lens in the Cosmic Lens All-Sky Survey (CLASS). B2045+265 is a four-image system with a maximum separation of 1.9 arcsec. A fifth radio compo…
Optical and near-infrared imaging of faint Gigahertz Peaked Spectrum sources
I. Snellen, R. T. Schilizzi, M. N. Bremer +5
A sample of 47 faint Gigahertz Peaked Spectrum (GPS) radio sources selected from the Westerbork Northern Sky Survey (WENSS, Rengelink et al. 1997), has been imaged in the optical a…
The 1.4 GHz light curve of GRB 970508
T. J. Galama, R. A. M. J. Wijers, M. Bremer +6
We report on Westerbork 1.4 GHz radio observations of the radio counterpart to -ray burst GRB~970508, between 0.80 and 138 days after this event. The 1.4 GHz light curve shows a…
A new sample of faint Gigahertz Peaked Spectrum radio sources
I. A. G. Snellen, R. T. Schilizzi, A. G. de Bruyn +4
The Westerbork Northern Sky Survey (WENSS) has been used to select a sample of Gigahertz Peaked Spectrum (GPS) radio sources at flux densities one to two orders of magnitude lower…
The edge-on spiral gravitational lens B1600+434
L. V. E. Koopmans, A. G. de Bruyn, N. Jackson
We present new observations of the gravitational lens (GL) system B1600+434, strongly suggesting that the lens is an edge-on spiral galaxy. These observations are used to constrain…
