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…
X-ray study of the double source plane gravitational lens system Eye of Horus observed with XMM-Newton
Keigo Tanaka, Ayumi Tsuji, Hiroki Akamatsu +19
A double source plane (DSP) system is a precious probe for the density profile of distant galaxies and cosmological parameters. However, these measurements could be affected by the…
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…
The cosmic evolution of the stellar massvelocity dispersion relation of early-type galaxies
Carlo Cannarozzo, Alessandro Sonnenfeld, Carlo Nipoti
We study the evolution of the observed correlation between central stellar velocity dispersion and stellar mass of massive ($M_*\gtrsim 3\times 10^{10}\,\mathr…
Discovery of an unusually compact lensed Lyman Break Galaxy from the Hyper Suprime-Cam Survey
Anton T. Jaelani, Anupreeta More, Alessandro Sonnenfeld +8
We report the serendipitous discovery of HSC J09040102, a quadruply-lensed Lyman break galaxy (LBG) in the Survey of Gravitationally-lensed Objects in Hyper Suprime-Cam Imaging…
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…
