A measurement of the Hubble constant from angular diameter distances to two gravitational lenses
Inh Jee, Sherry Suyu, Eiichiro Komatsu +3
The local expansion rate of the Universe is parametrized by the Hubble constant, , the ratio between recession velocity and distance. Different techniques lead to inconsistent…
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…
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…
