Three QSOs acting as strong gravitational lenses
F. Courbin, C. Faure, S. G. Djorgovski +8
We report the discovery of three new cases of QSOs acting as strong gravitational lenses on background emission line galaxies: SDSS J0827+5224 (zQSO = 0.293, zs = 0.412), SDSS J091…

A New Orientation Indicator for Radio-Quiet Quasars
Todd A. Boroson
The velocities of the [O III] 5007 and optical Fe II emission lines, measured relative to the systemic redshifts of 2265 QSOs by Hu et al. (2008), show the signature of a disklike…
