Microlensing probes the AGN structure of the lensed quasar J1131-1231
D. Sluse, J. -F. Claeskens, D. Hutsemékers +1
We present the analysis of single epoch long slit spectra of the three brightest images of the gravitationally lensed system J1131-1231. These spectra provide one of the clearest o…
Large scale correlations of quasar polarisation vectors: Hints of extreme scale structures?
Remi A. Cabanac, Damien Hutsemekers, Dominique Sluse +1
A survey measuring quasar polarization vectors has been started in two regions towards the North and South Galactic Poles. Here, We review the discovery of significant correlations…
VLT Observations of Two Unusual BAL Quasars
Patrick B. Hall, Damien Hutsemekers
Among the unusual broad absorption line quasars being found by the Sloan Digital Sky Survey (SDSS) are objects with much stronger absorption in Fe III than Fe II. These unusual lin…
Sub-arcsecond imaging and spectroscopy of the radio-loud highly polarized quasar PKS 1610-771
F. Courbin, D. Hutsemekers, G. Meylan +2
We report on imaging and spectroscopic observations of the radio-loud, highly polarized quasar PKS 1610-771 (z = 1.71). Our long-slit spectroscopy of the companion 4.55 arcseconds…
