Journal ArticleDOI
The Sloan Lens ACS Survey. I. A large spectroscopically selected sample of massive early-type lens galaxies
Adam S. Bolton,Adam S. Bolton,Scott Burles,Léon V. E. Koopmans,Tommaso Treu,Tommaso Treu,Leonidas A. Moustakas +6 more
TL;DR: The Sloan Lens ACS (SLACS) survey as mentioned in this paper was designed to detect bright early-type lens galaxies with faint lensed sources in order to increase the sample of known gravitational lenses suitable for detailed lensing, photometric, and dynamical modeling.
Journal ArticleDOI
The Sloan Lens ACS Survey. IV. The Mass Density Profile of Early-Type Galaxies out to 100 Effective Radii
Raphael Gavazzi,Tommaso Treu,Jason Rhodes,Léon V. E. Koopmans,Adam S. Bolton,Scott Burles,Richard Massey,Leonidas A. Moustakas +7 more
TL;DR: In this paper, the authors presented a weak-lensing analysis of 22 early-type (strong) lens galaxies, based on deep HST images obtained as part of the Sloan Lens ACS Survey.
Journal ArticleDOI
Tensions between the Early and the Late Universe
TL;DR: Tensions between the early and the late universe were discussed at the Kavli Institute for Theoretical Physics on July 15-17 2019 as mentioned in this paper to evaluate increasing evidence for these discrepancies, primarily in the value of the Hubble constant as well as ideas recently proposed to explain this tension.
Journal ArticleDOI
H0LiCOW - V. New COSMOGRAIL time delays of HE 0435-1223: H0 to 3.8 per cent precision from strong lensing in a flat ΛCDM model

Fassnacht,Tommaso Treu,Matthew W. Auger,Stefan Hilbert,Léon V. E. Koopmans,G. Meylan,N. Rumbaugh,Alessandro Sonnenfeld,Chiara Spiniello +19 more
TL;DR: In this article, a new measurement of the Hubble Constant H-0 and other cosmological parameters based on the joint analysis of three multiply imaged quasar systems with measured gravitational time delays is presented.
Journal ArticleDOI
Can minor merging account for the size growth of quiescent galaxies? new results from the candels survey
TL;DR: In this paper, the authors used deep infrared Wide Field Camera 3 data to probe the rest-frame optical structure of 935 galaxies selected with 0.4 10^(10.7) M_☉ in the UKIRT Ultra Deep Survey and GOODS-South fields of the CANDELS survey, finding that 13%-18% of quiescent hosts have likely physical companions with stellar mass ratios of 0.1 or greater.
