Probing the structure of the lensed quasar SDSS J1004+4112 through microlensing analysis of spectroscopic data
C. Fian, J. A. Muñoz, R. Forés-Toribio +5
We aim to reveal the sizes of the continuum and broad emission line (BEL) emitting regions in the gravitationally lensed quasar SDSS J1004+4112 by analyzing the unique signatures o…
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…
A Mass Model for the Lensing Cluster SDSS J1004+4112: Constraints From the Third Time Delay
R. Forés-Toribio, J. A. Muñoz, C. S. Kochanek +1
We have built a new model for the lens system SDSS J1004+4112 including the recently measured time delay of the fourth quasar image. This time delay has a strong influence on the i…
The Longest Delay: a 14.5 Yr Campaign to Determine the Third Time Delay in the Lensing Cluster SDSS~J1004+4112
J. A. Muñoz, C. S. Kochanek, J. Fohlmeister +3
We present new light curves for the four bright images of the five image cluster-lensed quasar gravitational lens system SDSS~J1004+4112. The light curves span 14.5 yr and allow me…
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…
