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…
The Initial Mass Function of Lens Galaxies from Quasar Microlensing
J. Jiménez-Vicente, E. Mediavilla
We present a new approach in the study of the Initial Mass function (IMF) in external galaxies based on quasar microlensing observations. We use measurements of quasar microlensing…
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…
Estimate of the Accretion Disk Size in the Gravitationally Lensed Quasar HE 0435-1223 using Microlensing Magnification Statistics
C. Fian, E. Mediavilla, J. Jiménez-Vicente +2
We present a measurement of the accretion disk size of the quadruple lensed quasar HE 0435-1223 from well-sampled 13-yr COSMOGRAIL optical light curves. Using accurate time delays…
Systematic Redshift of the Fe III UV Lines in Quasars. Measuring Supermassive Black Hole Masses under the Gravitational Redshift Hypothesis
E. Mediavilla, J. JimÉnez-Vicente, C. Fian +4
We find that the Fe III2039-2113 spectral feature in quasars appears systematically redshifted by amounts accountable under the hypothesis of gravitational redshift induced by…
