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…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). IV. Lensed quasar search in the HSC survey
James H. H. Chan, Sherry H. Suyu, Alessandro Sonnenfeld +9
Strong gravitationally lensed quasars provide powerful means to study galaxy evolution and cosmology. We use Chitah to hunt for new lens systems in the Hyper SuprimeCam Subaru S…
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…
Cosmic dissonance: new physics or systematics behind a short sound horizon?
Nikki Arendse, Radosław J. Wojtak, Adriano Agnello +12
Persistent tension between low-redshift observations and the Cosmic Microwave Background radiation (CMB), in terms of two fundamental distance scales set by the sound horizon …
COSMOGRAIL XVIII: time delays of the quadruply lensed quasar WFI2033-4723
V. Bonvin, M. Millon, J. H. H. Chan +26
We present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2m Leonhard Euler Swiss telescope, 13 years…
The Hubble Constant determined through an inverse distance ladder including quasar time delays and Type Ia supernovae
S. Taubenberger, S. H. Suyu, E. Komatsu +7
Context. The precise determination of the present-day expansion rate of the Universe, expressed through the Hubble constant , is one of the most pressing challenges in modern…
