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…
MEGADES: MEGARA Galaxy Discs Evolution Survey. Data Release I: central fields
M. Chamorro-Cazorla, A. Gil de Paz, A. Castillo-Morales +12
The main interest of the Science Team for the exploitation of the MEGARA instrument at the 10.4m Gran Telescopio Canarias (GTC hereafter) is devoted to the study of nearby galaxies…
Strong Chromatic Microlensing in HE0047-1756 and SDSS1155+6346
Karina Rojas, Verónica Motta, Evencio Mediavilla +3
We use spectra of the double lensed quasars HE0047-1756 and SDSS1155+6346 to study their unresolved structure through the impact of microlensing. There is no significant evidence o…
