Detection of the Galaxy Lensing the Doubly–imaged Quasar Sbs 1520+530
H band observations with a spatial resolution of 0. 15 carried out with the Canada-France-Hawaii Telescope adaptive optics system show a galaxy between the components of the double BAL QSO SBS 1520+530, thereby confirming this system as a gravitational lens. The galaxy is located 0. 40 from the fainter of the two QSO images and is offset 0. 12 from the line joining them. The H magnitude of the ...
متن کاملThe lensing system towards the doubly imaged quasar SBS 1520 + 530 ⋆
The gravitational potential responsible for the lensing effect in SBS 1520+530 is studied over length scales from a few arc-seconds to a few arc-minutes. For this purpose, we use sharply deconvolved Hubble Space Telescope images in the optical and near-IR, in combination with ground based optical data obtained over a wider field-of-view. In particular, we have carried out a multi-color analysis...
متن کاملAn Optical Time-Delay for the Lensed BAL Quasar
We present optical V and i-band light curves of the gravitationally lensed BAL quasar HE 2149−2745. The data, obtained with the 1.5m Danish Telescope (ESO-La Silla) between October 1998 and December 2000, are the first from a long-term project aimed at monitoring selected lensed quasars in the Southern Hemisphere. A time delay of 103±12 days is determined from the light curves. In addition, VLT...
متن کاملRedshift estimate of a gravitational lens from the observed reddening of a multiply imaged quasar
Light rays from a multiply imaged quasar usually sample different path lengths across the deflector. Extinction in the lensing galaxy may thus lead to a differential obscuration and reddening between the observed macro-lensed QSO images. These effects naturally depend on the precise shape of the extinction law and on the redshift of the lens. By means of numerical Monte-Carlo simulations, using...
متن کاملUnusual high - redshift radio BAL quasar 1624 + 3758
We present observations of the most radio-luminous BAL quasar known, 1624+3758, at redshift z = 3.377. The quasar has several unusual properties: (1) The FeII UV191 1787-˚ A emission line is very prominent. (2) The BAL trough (BALnicity index 2990 kms −1) is detached by 21000 kms −1 and extends to velocity v =-29000 kms −1. There are additional intrinsic absorbers at-1900 and-2800 kms −1. (3) T...
