Abundance of LIGO/Virgo Black Holes from Microlensing Observations of Quasars with Reverberation Mapping Size Estimates
A. Esteban-Gutiérrez, E. Mediavilla, J. Jiménez-Vicente +3
Assuming a population of Black Holes (BHs) with masses in the range inferred by LIGO/Virgo from BH mergers, we use quasar microlensing observations to estimate their abundances. We…
Limiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
A. Esteban-Gutiérrez, E. Mediavilla, J. Jiménez-Vicente +3
We present a simple but general argument that strongly limits the abundance of Primordial Black Holes (PBHs) (or other unknown population of compact objects) with masses similar to…
Revealing the structure of the lensed quasar Q 0957+561: I. Accretion disk size
C. Fian, E. Mediavilla, J. Jiménez-Vicente +6
We aim to use signatures of microlensing induced by stars in the foreground lens galaxy to infer the size of the accretion disk in the gravitationally lensed quasar Q 0957+561. The…
Revealing the structure of the lensed quasar Q 0957+561: III. SMBH mass via gravitational redshift
C. Fian, E. Mediavilla, J. Jiménez-Vicente +4
We intend to use the impact of microlensing on the Fe III emission line blend along with a measure of its gravitational redshift to estimate the mass of the quasar's central superm…
Microlensing of the broad emission lines in 27 gravitationally lensed quasars. Broad line region structure and kinematics
C. Fian, E. Mediavilla, V. Motta +4
We aim to study the structure and kinematics of the broad line region (BLR) of a sample of 27 gravitationally lensed quasars with up to five different epochs of observation. This s…
