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…
A Second-Order Moment of Microlensing Variability as a Novel Tool in Extragalactic Research
Eduardo Guerras, Xinyu Dai, Evencio Mediavilla
We define a second-order moment of the observational differential microlensing curves that can be used to impose constraints on physical properties of lensed quasars. We show that…
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…
Probing Planets in Extragalactic Galaxies Using Quasar Microlensing
Xinyu Dai, Eduardo Guerras
Previously, planets have been detected only in the Milky Way galaxy. Here, we show that quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by s…
