Point-spread function reconstruction of adaptive-optics imaging: Meeting the astrometric requirements for time-delay cosmography
Geoff C. -F. Chen, Tommaso Treu, Christopher D. Fassnacht +3
Astrometric precision and knowledge of the point spread function are key ingredients for a wide range of astrophysical studies including time-delay cosmography in which strongly le…
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…
A method for efficient measurement of gravitational lens time delays
G. Gürkan, N. Jackson, I. W. A. Browne +3
The Hubble constant value is currently known to 10% accuracy unless assumptions are made for the cosmology (Sandage et al. 2006). Gravitational lens systems provide another probe o…
