VDES J2325-5229 a z=2.7 gravitationally lensed quasar discovered using morphology independent supervised machine learning
Fernanda Ostrovski, Richard G. McMahon, Andrew J. Connolly +56
We present the discovery and preliminary characterization of a gravitationally lensed quasar with a source redshift and image separation of lensed by a foregrou…
Gravitationally Lensed Quasars in Gaia: II. Discovery of 24 Lensed Quasars
Cameron A. Lemon, Matthew W. Auger, Richard G. McMahon +1
We report the discovery, spectroscopic confirmation and preliminary characterisation of 24 gravitationally lensed quasars identified using Gaia observations. Candidates were select…
The Discovery of a Five-Image Lensed Quasar at z = 3.34 using PanSTARRS1 and Gaia
Fernanda Ostrovski, Cameron A. Lemon, Matthew W. Auger +8
We report the discovery, spectroscopic confirmation, and mass modelling of the gravitationally lensed quasar system PS J0630-1201. The lens was discovered by matching a photometric…
Discovery of two gravitationally lensed quasars in the Dark Energy Survey
Adriano Agnello, Tommaso Treu, Fernanda Ostrovski +77
We present spectroscopic confirmation of two new lensed quasars via data obtained at the 6.5m Magellan/Baade Telescope. The lens candidates have been selected from the Dark Energy…
