Revealing the structure of the lensed quasar Q 0957+561: I. Accretion disk size
C. Fian, E. Mediavilla, J. Jiménez-Vicente +6
We aim to use signatures of microlensing induced by stars in the foreground lens galaxy to infer the size of the accretion disk in the gravitationally lensed quasar Q 0957+561. The…
Microlensing of the broad emission lines in 27 gravitationally lensed quasars. Broad line region structure and kinematics
C. Fian, E. Mediavilla, V. Motta +4
We aim to study the structure and kinematics of the broad line region (BLR) of a sample of 27 gravitationally lensed quasars with up to five different epochs of observation. This s…
Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad Line Region
E. Mediavilla, J. Jiménez-Vicente, J. Mejí A-Restrepo +5
Assuming a gravitational origin for the Fe III2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we obtain individual me…
Microlensing Analysis for the gravitational lens systems SDSS0924+0219, Q1355-2257, and SDSS1029+2623
K. Rojas, V. Motta, E. Mediavilla +3
We use spectroscopic observations of the gravitationally lensed systems SDSS0924+0219(BC), Q1355-2257(AB), and SDSS1029+2623(BC) to analyze microlensing and dust extinction in the…
Spectroscopy and polarimetry of the gravitationally lensed quasar SDSS J1004+4112 with the 6m SAO RAS telescope
L. Č. Popović, V. L. Afanasiev, A. Moiseev +5
We present new spectroscopic and polarimetric observations of the gravitational lens SDSS J1004+4112 taken with the 6m telescope of the Special Astrophysical Observatory (SAO, Russ…
Measuring Supermassive Black Hole Masses: Correlation between the Redshifts of the Fe III UV Lines and the Widths of Broad Emission Lines
E. Mediavilla, J. JimÉnez-Vicente, J. MejÍa-Restrepo +5
We test the recently proposed (Mediavilla et al. 2018) black hole mass scaling relationship based on the redshift {with respect to the quasar's rest frame} of the Fe III2039-21…
