TL;DR: In this paper, the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme was used to support the discovery of the structure of the universe in Brazil.
The mass profile of early-type galaxies in overdense environments: the case of the double source plane gravitational lens SL2SJ02176-0513
H. Tu,H. Tu,Raphael Gavazzi,Raphael Gavazzi,Marceau Limousin,Marceau Limousin,Remi A. Cabanac,Philip J. Marshall,Bernard Fort,Tommaso Treu,Roser Pello,Eric Jullo,Jean-Paul Kneib,J.-F. Sygnet +13 more
TL;DR: In this article, the authors used multicolor photometry and lensing geometry to estimate the stellar mass of the main lens galaxy in the presence of two multiply-imaged systems at different redshifts.

TL;DR: In this paper, the authors presented the MUSE Deep Lensed Field (MDLF) program, which is aimed at unveiling the very faint population of high redshift sources that are magnified by strong gravitational lensing and to significantly increase the number of constraints for the lens model.

TL;DR: In this paper, the authors present time-delay estimates for the quadruply imaged quasar PG 1115+080, based on almost daily observations for seven months at the ESO MPIA 2.2m telescope at La Silla Observatory, reaching a signalto-noise ratio of about 1000 per quasar image.

Purely dry mergers do not explain the observed evolution of massive early-type galaxies since z ∼ 1
TL;DR: In this article, the authors constructed a theoretical model for the joint evolution of the size and mass density profile slope γ' driven by dry mergers occurring at rates given by cosmological simulations.
