Revealing the inner workings of the lensed quasar SDSS J1339+1310: Insights from microlensing analysis
C. Fian, J. A. Muñoz, J. Jiménez-Vicente +4
We aim to unveil the structure of the continuum and broad-emission line (BEL) emitting regions in the gravitationally lensed quasar SDSS J1339+1310 by examining the distinct signat…
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…
Constraints on the Abundance of PBHs from X-ray Quasar Microlensing Observations: Substellar to Planetary Mass Range
A. Esteban-Gutiérrez, E. Mediavilla, J. Jiménez-Vicente +1
We use X-ray observations of quasar microlensing (sensitive to smaller compact objects than in the optical) to study the possible presence of a population of low mass black holes (…
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…
