H0LiCOW VIII. A weak lensing measurement of the external convergence in the field of the lensed quasar HE04351223
O. Tihhonova, F. Courbin, D. Harvey +10
We present a weak gravitational lensing measurement of the external convergence along the line of sight to the quadruply lensed quasar HE04351223. Using deep r-band images f…
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…
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…
