Wide-Field InfraRed Survey Telescope (WFIRST) Final Report
J. Green, P. Schechter, C. Baltay +51
In December 2010, NASA created a Science Definition Team (SDT) for WFIRST, the Wide Field Infra-Red Survey Telescope, recommended by the Astro 2010 Decadal Survey as the highest pr…
STRIDES: Automated uniform models for 30 quadruply imaged quasars
T. Schmidt, T. Treu, S. Birrer +68
Gravitational time delays provide a powerful one step measurement of , independent of all other probes. One key ingredient in time delay cosmography are high accuracy lens mod…
Finding quadruply imaged quasars with machine learning. I. Methods
A. Akhazhanov, A. More, A. Amini +68
Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They are very rare in the sky -- only a few tens are known to date -- and yet they provide unique inform…
Models of the strongly lensed quasar DES J0408-5354
Adriano Agnello, Huan Lin, L. Buckley-Geer +82
We present gravitational lens models of the multiply imaged quasar DES J0408-5354, recently discovered in the Dark Energy Survey (DES) footprint, with the aim of interpreting its r…
Gravitationally lensed quasars in Gaia -- IV. 150 new lenses, quasar pairs, and projected quasars
C. Lemon, T. Anguita, M. Auger +8
We report the spectroscopic follow-up of 175 lensed quasar candidates selected using Gaia Data Release 2 observations following Lemon et al. 2019. Systems include 86 confirmed lens…
