Gaia GraL: Gaia DR2 gravitational lens systems - IV. Keck/LRIS spectroscopic confirmation of GRAL 113100−441959 and model prediction of time delays

Wertz, O. Stern, D. Krone-Martins, A.

We report the spectroscopic confirmation and modeling of the quadruply imaged quasar GRAL 113100–441959, the first gravitational lens (GL) to be discovered from a machine learning technique that only relies on the relative positions and fluxes of the observed images without considering colour informations. Follow-up spectra obtained with...
