Microlensing analysis of 14.5-year light curves in SDSS J1004+4112: Quasar accretion disk size and intracluster stellar mass fraction

R. Forés-Toribio, J. A. Muñoz, C. Fian +2

Context. The gravitational lens system SDSS J1004+4112 was the first known example of a quasar lensed by a galaxy cluster. The interest in this system has been renewed following th…

Single-epoch and Differential Astrometric Microlensing of Quasars

R. Forés-Toribio, E. Mediavilla, J. A. Muñoz +3

We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing). O…

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…

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…
