We performed VLBA observations of the Broad Absorption Line Quasar FIRST,J155633.8+351758, the first radio loud BALQSO. Our observations at 15.3 GHz partially resolved a secondary component at positional angle (PA) $approx 35^{circ}$. We combine this determination of the radio jet projection on the sky plane, with the constraint that the jet is viewed within $14.3^{circ}$ of the line of sight (as implied by the high variability brightness temperature) and with the position angle (PA) of the optical/UV continuum polarization in order to study the quasar geometry. Within the context of the standard model, the data indicates a dusty torus (scattering surface) with a symmetry axis tilted relative to the accretion disk normal and a polar broad absorption line outflow aligned with the accretion disk normal. We compare this geometry to that indicated by the higher resolution radio data, brightness temperature and optical/UV continuum polarization PA of a similar high optical polarization BALQSO, Mrk,231. A qualitatively similar geometry is found in these two polar BALQSOs; the continuum polarization is determined primarily by the tilt of the dusty torus.
We report the emergence of a high velocity, broad absorption line outflow in the luminous quasar Ton 34, at z=1.928. The outflow is detected through an ultraviolet CIV broad absorption line, in a spectrum obtained in January 2006 by the Sloan Digital
We present the first near-IR spectroscopy of the z=1.5 radio-loud BALQSO FIRST J155633.8+351758. Both the Balmer decrement and the slope of the rest-frame UV-optical continuum independently suggest a modest amount of extinction along the line of sigh
(Abridged) We investigate the observational characteristics of BLR geometries in which the BLR clouds bridge the gap, both in distance and scale height, between the outer accretion disc and the hot dust, forming an effective surface of a bowl. The ga
The existence of intermediate-width emission line regions (IELRs) in active galactic nuclei has been discussed for over two decades. A consensus, however, is yet to be arrived at due to the lack of convincing evidence for their detection. We present
In this paper we present near infrared (NIR) imaging data of the host galaxy of the broad absorption line quasar (BALQ) at z=2.169, serendipitously found close to 3C48. The data were obtained with the ESO-VLT camera ISAAC during period 67. We find ex
