Gaia GraL: Gaia DR2 Gravitational Lens Systems. IV. Keck/LRIS spectroscopic confirmation of GRAL113100-441959 and model prediction of time-delays
Olivier Wertz, Daniel Stern, Alberto Krone-Martins +14
We report the spectroscopic confirmation and modeling of the quadruply imaged quasar GRAL113100-441959, the first gravitational lens (GL) to be discovered mainly from astrometric c…
Gaia GraL: Gaia DR2 Gravitational Lens Systems. III. A systematic blind search for new lensed systems
L. Delchambre, A. Krone-Martins, O. Wertz +13
Aims: In this work, we aim to provide a reliable list of gravitational lens (GL) candidates based on a search performed over the entire Gaia Data Release 2 (Gaia DR2). We also show…
Gaia GraL II - Gaia DR2 Gravitational Lens Systems: The Known Multiply Imaged Quasars
C. Ducourant, O. Wertz, A. Krone-Martins +12
Thanks to its spatial resolution the ESA/Gaia space mission offers a unique opportunity to discover new multiply-imaged quasars and to study the already known lensed systems at sub…
Gaia DR2 Gravitational Lens Systems I: New lensed quasar candidates around known quasars
A. Krone-Martins, L. Delchambre, O. Wertz +11
Context. Strong gravitationally lensed quasars are among the most interesting and useful observable extragalactic phenomena. Because their study constitutes a unique tool in variou…
