Journal ArticleDOI
The SL2S galaxy-scale lens sample. V. dark matter halos and stellar IMF of massive early-type galaxies out to redshift 0.8
Alessandro Sonnenfeld,Tommaso Treu,Tommaso Treu,Philip J. Marshall,Sherry H. Suyu,Raphael Gavazzi,Matthew W. Auger,Carlo Nipoti +7 more
TL;DR: In this paper, the authors investigate the cosmic evolution of the internal structure of massive early-type galaxies over half of the age of the universe and perform a joint lensing and stellar dynamics analysis of a sample of 81 strong lenses from the Strong Lensing Legacy Survey and Sloan ACS Lens Survey and combine the results with a hierarchical Bayesian inference method to measure the distribution of dark matter mass and stellar initial mass function.
Journal ArticleDOI
Dissecting the Gravitational Lens B1608+656. I. Lens Potential Reconstruction
Sherry H. Suyu,Sherry H. Suyu,Sherry H. Suyu,P. J. Marshall,Roger Blandford,Roger Blandford,Christopher D. Fassnacht,Luitje Koopmans,John McKean,Tommaso Treu,Tommaso Treu +10 more
TL;DR: In this paper, a pixelated approach to model the lens potential and source-intensity distribution simultaneously is presented, which makes iterative and perturbative corrections to an initial potential model.
Journal ArticleDOI
The sl2s galaxy-scale lens sample. iii. lens models, surface photometry, and stellar masses for the final sample
Alessandro Sonnenfeld,Raphael Gavazzi,Sherry H. Suyu,Sherry H. Suyu,Sherry H. Suyu,Tommaso Treu,Philip J. Marshall +6 more
TL;DR: In this paper, the authors used HST images and Canada-France-Hawaii Telescope (CFHT) near-infrared ground-based images for the final sample of 56 candidate galaxy-scale lenses uncovered in the CFHT Legacy Survey as part of the Strong Lensing in the Legacy Survey project.
Journal ArticleDOI
The properties of field elliptical galaxies at intermediate redshift – III. The Fundamental Plane and the evolution of stellar populations from z≈0.4 to z=0
TL;DR: In this paper, a sample of 25 field early-type galaxies, in the redshift range z≈0.1-0.5, selected on the basis of colours and morphology from the Medium Deep Survey (MDS) of the Hubble Space Telescope (HST), was used to study the evolution of the Fundamental Plane (FP) with redshift.
Journal ArticleDOI
The Stellar Velocity Dispersion of the Lens Galaxy in MG 2016+112 at z = 1.004*
Léon V. E. Koopmans,Tommaso Treu +1 more
TL;DR: In this article, the stellar velocity dispersion of the early-type lens galaxy D in the system MG 2016+112 (z = 1.004), determined from a spectrum obtained with the Echelle Spectrograph and Imager on the W. M. Keck II Telescope, as part of the Lenses Structure and Dynamics Survey, was presented.
