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…
Twisted quasar light curves: implications for continuum reverberation mapping of accretion disks
J. H-H. Chan, M. Millon, V. Bonvin +1
With the advent of high-cadence and multi-band photometric monitoring facilities, continuum reverberation mapping is becoming of increasing importance to measure the physical size…
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…
