The radiogalaxy 3C324 has recently raised considerable interest as one of the most distant (redshift z = 1.206) and luminous known galaxies. Here we report new observations of this object at Canada–France–Hawaii Telescope which confirm our previous predictions of the presence of an intervening gravitational lens. First, a multiple structure is revealed by our charge-coupled device (CCD) broadband imagery. Second, following our previous identification in the 3C324 spectrum of an additional line… 

New results from the gravitational telescope

New improvements in extragalactic research have recently increased the number of sources at high redshift, QSOs and also galaxies. Gravitational magnification or lensing by foreground matter are able

Lensing by Distant Clusters: HST Observations of Weak Shear in the Field of 3C 324

We present the detection of weak gravitational lensing in the field of the radio galaxy 3C 324 (z = 1.206) using deep HST imaging. From an analysis of the shapes of faint R = 24.5-27.5 galaxies in

New views through the gravitational telescope

New improvements in extragalactic research have recently increased the number of sources at high redshift, i.e., QSOs and especially galaxies. Gravitational lensing/magnification events are more

Observational aspects of gravitational lensing

In this review on the recent observational aspects of gravitational lensing, I first present the various systematic optical surveys for multiply lensed extragalactic objects that are being carried

Optical observations of gravitational lenses

We report here on some of the major developments achieved on optical observations of gravitational lenses since the last conference devoted to “Gravitational Lensing” (Toulouse, September 1989).

Gravitational lensing in observational cosmology

This paper reviews some previous theoretical and observational results concerning the various effects of gravitational lensing, and also presents still unpublished results in this field. The

8.4 GHz High-Resolution Observations of Fanaroff-Riley II 3CR Radio Sources with 0.3 < z < 2.0. II. Ten New Images

VLA observations at 8.4 GHz of two Fanaroff-Riley class II (FR II) radio galaxies (RGs; 3C 265 and 3C 324) and eight FR II quasars (QSRs; 3C 175, 3C 204, 3C 215, 3C 249.1, 3C 263, 3C 336, 3C 351, and

Gravitational magnification effects on distant 3CR galaxies

A photometric survey of 27 3CR galaxies with z>1 is presented. Unprecedented image quality of the data (mean FWHM=O"75 for the sample) have allowed us to find that ] of the galaxies are made of 2 to

Extended optical line emission in powerful radio galaxies

Optical and radio observations of nearby and distant powerful radio galaxies with extended optical emission-line regions are discussed. Comparisons of optical emission-line images with radio
