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…

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

A SHARP view of H0LiCOW: from three time-delay gravitational lens systems with adaptive optics imaging

Geoff C. -F. Chen, Christopher D. Fassnacht, Sherry. H. Suyu +20

We present the measurement of the Hubble Constant, , with three strong gravitational lens systems. We describe a blind analysis of both PG1115+080 and HE0435-1223 as well as a…

H0LiCOW XIII. A 2.4% measurement of from lensed quasars: tension between early and late-Universe probes

Kenneth C. Wong, Sherry H. Suyu, Geoff C. -F. Chen +23

We present a measurement of the Hubble constant () and other cosmological parameters from a joint analysis of six gravitationally lensed quasars with measured time delays. A…

H0LiCOW XII. Lens mass model of WFI2033-4723 and blind measurement of its time-delay distance and

Cristian E. Rusu, Kenneth C. Wong, Vivien Bonvin +15

We present the lens mass model of the quadruply-imaged gravitationally lensed quasar WFI2033-4723, and perform a blind cosmographical analysis based on this system. Our analysis co…
