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…
Deficit of Luminous and Normal Red Galaxies in Cosmic Voids
Sean Bruton, Xinyu Dai, Eduardo Guerras +1
We construct a sample of 10,680 wall galaxies and 3,064 void galaxies with by cross referencing a void catalog from literature with Baryon Oscillation Spectrosco…
Confirmation of Planet-Mass Objects in Extragalactic Systems
Saloni Bhatiani, Xinyu Dai, Eduardo Guerras
Quasar microlensing serves as a unique probe of discrete objects within galaxies and galaxy clusters. Recent advancement of the technique shows that it can constrain planet-scale o…
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…
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…
