The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2017/2018 follow-up campaign: Discovery of 10 lensed quasars and 10 quasar pairs
C. Lemon, M. W. Auger, R. McMahon +65
We report the results of the STRong lensing Insights from the Dark Energy Survey (STRIDES) follow-up campaign of the late 2017/early 2018 season. We obtained spectra of 65 lensed q…
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…
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…
Unified lensing and kinematic analysis for any elliptical mass profile
Anowar J. Shajib
We demonstrate an efficient method to compute the strong-gravitational-lensing deflection angle and magnification for any elliptical surface-density profile. This method solves a n…
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…
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…
H0LiCOW X: Spectroscopic/imaging survey and galaxy-group identification around the strong gravitational lens system WFI2033-4723
D. Sluse, C. E. Rusu, C. D. Fassnacht +65
Galaxies and galaxy groups located along the line of sight towards gravitationally lensed quasars produce high-order perturbations of the gravitational potential at the lens positi…
