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…
Is every strong lens model unhappy in its own way? Uniform modelling of a sample of 13 quadruply+ imaged quasars
A. J. Shajib, S. Birrer, T. Treu +70
Strong-gravitational lens systems with quadruply-imaged quasars (quads) are unique probes to address several fundamental problems in cosmology and astrophysics. Although they are i…
Models of gravitational lens candidates from Space Warps CFHTLS
Rafael Küng, Prasenjit Saha, Ignacio Ferreras +9
We report modelling follow-up of recently-discovered gravitational-lens candidates in the Canada France Hawaii Telescope Legacy Survey. Lens modelling was done by a small group of…
Models of the strongly lensed quasar DES J0408-5354
Adriano Agnello, Huan Lin, L. Buckley-Geer +82
We present gravitational lens models of the multiply imaged quasar DES J0408-5354, recently discovered in the Dark Energy Survey (DES) footprint, with the aim of interpreting its r…
Discovery of the Lensed Quasar System DES J0408-5354
H. Lin, E. Buckley-Geer, A. Agnello +78
We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was…
Luminous Satellites II: Spatial Distribution, Luminosity Function and Cosmic Evolution
A. M. Nierenberg, M. W. Auger, T. Treu +3
We infer the normalization and the radial and angular distributions of the number density of satellites of massive galaxies () between redshifts 0.1…
