The Sloan Lens ACS Survey. I. A large spectroscopically selected sample of massive early-type lens galaxies

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

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

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.
