Quasar lenses and pairs in the VST-ATLAS and Gaia
A. Agnello, P. L. Schechter, N. D. Morgan +10
We report on discovery results from a quasar lens search in the ATLAS public footprint, extending quasar lens searches to a regime without band or fiber-spectroscopic informati…
DES meets Gaia: discovery of strongly lensed quasars from a multiplet search
A. Agnello, H. Lin, N. Kuropatkin +69
We report the discovery, spectroscopic confirmation and first lens models of the first two, strongly lensed quasars from a combined search in WISE and Gaia over the DES footprint.…
Discovery of three strongly lensed quasars in the Sloan Digital Sky Survey
Peter R. Williams, Adriano Agnello, Tommaso Treu +12
We present the discovery of 3 quasar lenses in the Sloan Digital Sky Survey (SDSS), selected using two novel photometry-based selection techniques. The J0941+0518 system, with two…
COSMOGRAIL XVI: Time delays for the quadruply imaged quasar DES J0408-5354 with high-cadence photometric monitoring
F. Courbin, V. Bonvin, E. Buckley-Geer +74
We present time-delay measurements for the new quadruply imaged quasar DES J0408-5354, the first quadruply imaged quasar found in the Dark Energy Survey (DES). Our result is made p…
Probing the Broad Line Region and the Accretion Disk in the Lensed Quasars HE0435-1223, WFI2033-4723, and HE2149-2745 using Gravitational Microlensing
V. Motta, E. Mediavilla, K. Rojas +3
We use single-epoch spectroscopy of three gravitationally lensed quasars, HE0435-1223, WFI2033-4723, and HE2149-2745, to study their inner structure (BLR and continuum source). We…
