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…
Microlensing and Intrinsic Variability of the Broad Emission Lines of Lensed Quasars
C. Fian, Eduardo Guerras, E. Mediavilla +5
We study the BELs in a sample of 11 gravitationally lensed quasars with at least two epochs of observation to identify intrinsic variability and to disentangle it from microlensing…
