... Willem de Vries, 1,2 John A. Biretta, 1 Stefi A. Baum 1 We present HST/WFPC2 broadband red and linear ramp filter (isolating redshifted [OII] 3727 ) observations and subarcsecond resolution 15, 22 and 43 GHz VLA observations of the radio-loud quasar 3C380 ...
... Its importance as an astrophysical tool first became apparent with the realisation (in 1979) that the quasar pair Q0957+561 actually comprised two lensed images of the same background quasar. ...
... Compared to quasars or galaxies, Type Ia SNe represent a population of sources with well-known intrinsic properties and could be used to detect gravitational lensing even in the absence of multiple or highly distorted images. ...
