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…

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…

Measuring accretion disk sizes of lensed quasars with microlensing time delay in multi-band light curves

J. H. H. Chan, K. Rojas, M. Millon +3

Time-delay cosmography in strongly lensed quasars offer an independent way of measuring the Hubble constant, . However, it has been proposed that the combination of microlensi…

HOLISMOKES -- II. Identifying galaxy-scale strong gravitational lenses in Pan-STARRS using convolutional neural networks

R. Canameras, S. Schuldt, S. H. Suyu +6

We present a systematic search for wide-separation (Einstein radius >1.5"), galaxy-scale strong lenses in the 30 000 sq.deg of the Pan-STARRS 3pi survey on the Northern sky. With l…

Microlensing Analysis for the gravitational lens systems SDSS0924+0219, Q1355-2257, and SDSS1029+2623

K. Rojas, V. Motta, E. Mediavilla +3

We use spectroscopic observations of the gravitationally lensed systems SDSS0924+0219(BC), Q1355-2257(AB), and SDSS1029+2623(BC) to analyze microlensing and dust extinction in the…

The Most Powerful Lenses in the Universe: Quasar Microlensing as a Probe of the Lensing Galaxy

David Pooley, Timo Anguita, Saloni Bhatiani +14

Optical and X-ray observations of strongly gravitationally lensed quasars (especially when four separate images of the quasar are produced) determine not only the amount of matter…
