Testing Einstein's Equivalence Principle and its Cosmological Evolution from Quasar Gravitational Redshifts
E. Mediavilla, J. JimÉnez-Vicente
We propose and apply a new test of Einstein's Equivalence Principle (EEP) based on the gravitational redshift induced by the central super massive black hole of quasars in the surr…
The Impact of the Mass Spectrum of Lenses in Quasar Microlensing Studies. Constraints on a Mixed Population of Primordial Black Holes and Stars
A. Esteban-Gutiérrez, N. Agües-Paszkowsky, E. Mediavilla +3
We show that quasar microlensing magnification statistics induced by a population of point microlenses distributed according to a mass-spectrum can be very well approximated by tha…
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…
