H0LiCOW - IX. Cosmographic analysis of the doubly imaged quasar SDSS 1206+4332 and a new measurement of the Hubble constant
S. Birrer, T. Treu, C. E. Rusu +15
We present a blind time-delay strong lensing (TDSL) cosmographic analysis of the doubly imaged quasar SDSS 1206+4332. We combine the relative time delay between the quasar images,…
Is every strong lens model unhappy in its own way? Uniform modelling of a sample of 13 quadruply+ imaged quasars
A. J. Shajib, S. Birrer, T. Treu +70
Strong-gravitational lens systems with quadruply-imaged quasars (quads) are unique probes to address several fundamental problems in cosmology and astrophysics. Although they are i…
Constraining the microlensing effect on time delays with new time-delay prediction model in measurements
Geoff C. -F. Chen, James H. H. Chan, Vivien Bonvin +14
Time-delay strong lensing provides a unique way to directly measure the Hubble constant (). The precision of the measurement depends on the uncertainties in the time…
Time Delay Lens Modeling Challenge: I. Experimental Design
Xuheng Ding, Tommaso Treu, Anowar J. Shajib +11
Strong gravitational lenses with measured time delay are a powerful tool to measure cosmological parameters, especially the Hubble constant (). Recent studies show that by com…
