Revealing the structure of the lensed quasar Q 0957+561 III. Constraints on the size of the broad-line region

C. Fian, J. A. Muñoz, E. Mediavilla +6

Our aim is to examine the size, kinematics, and geometry of the broad-line region (BLR) in the double-lensed quasar Q 0957+561 by analyzing the impact of microlensing on various re…

Black Hole masses for 14 gravitational lensed quasars

A. Melo, V. Motta, J. Mejía-Restrepo +7

We estimate black hole masses (M) for 14 gravitationally lensed quasars using the Balmer lines along with estimates based on MgII and CIV emission lines for four and two…

First black hole mass estimation for the quadruple lensed system WGD2038-4008

A. Melo, V. Motta, N. Godoy +6

The quadruple lensed system WGD2038-4008 was recently discovered with the help of new techniques and observations. Even though black hole mass has been estimated for lensed quasars…

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…
