SHARP VIII: J0924+0219 lens mass distribution and time-delay prediction through adaptive-optics imaging
Geoff C. -F. Chen, Christopher D. Fassnacht, Sherry H. Suyu +6
Strongly lensed quasars can provide measurements of the Hubble constant () independent of any other methods. One of the key ingredients is exquisite high-resolution imaging…
Joint constraints on thermal relic dark matter from strong gravitational lensing, the Lyman- forest, and Milky Way satellites
Wolfgang Enzi, Riccardo Murgia, Oliver Newton +10
We derive joint constraints on the warm dark matter (WDM) half-mode scale by combining the analyses of a selection of astrophysical probes: strong gravitational lensing with extend…
TDCOSMO IV: Hierarchical time-delay cosmography -- joint inference of the Hubble constant and galaxy density profiles
S. Birrer, A. J. Shajib, A. Galan +24
The H0LiCOW collaboration inferred via gravitational lensing time delays a Hubble constant km s, describing deflector mass density pro…
Time Delay Lens Modelling Challenge
X. Ding, T. Treu, S. Birrer +26
In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool to measure the Hubble constant . However, published…
TDCOSMO. I. An exploration of systematic uncertainties in the inference of from time-delay cosmography
M. Millon, A. Galan, F. Courbin +22
Time-delay cosmography of lensed quasars has achieved 2.4% precision on the measurement of the Hubble constant, . As part of an ongoing effort to uncover and control systemati…
STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354
A. J. Shajib, S. Birrer, T. Treu +88
We present a blind time-delay cosmographic analysis for the lens system DES J04085354. This system is extraordinary for the presence of two sets of multiple images at different…
