SDSSJ2222+2745 A Gravitationally Lensed Sextuple Quasar with Maximum Image Separation of 15.1" Discovered in the Sloan Giant Arcs Survey
H. Dahle,Michael D. Gladders,Keren Sharon,Matthew B. Bayliss,E. Wuyts,L. E. Abramson,Benjamin P. Koester,Nicolaas E. Groeneboom,T. E. Brinckmann,M. T. Kristensen,M. O. Lindholmer,A. Nielsen,J.-K. Krogager,J. P. U. Fynbo +13 more
TL;DR: In this paper, the authors reported the discovery of a unique gravitational lens system, SDSSJ2222+2745, producing five spectroscopically confirmed images of a z_s=2.82 quasar lensed by a foreground galaxy cluster at z_l=0.49.

Metal Deficiency in Two Massive Dead Galaxies at $z\sim2$
T. Morishita,L. E. Abramson,Tommaso Treu,Xin Wang,Gabriel B. Brammer,Patrick L. Kelly,Massimo Stiavelli,Tucker Jones,Kasper B. Schmidt,Michele Trenti,Benedetta Vulcani +10 more
TL;DR: In this paper, the authors report the discovery of two lensed massive early-type galaxies, which appear markedly metal deficient given this scenario, and suggest that evolutionary paths other than dry minor-merging are required for these massive galaxies.

Late Bloomer Galaxies: Growing Up in Cosmic Autumn
TL;DR: In this paper, an improved methodology for deriving star formation histories (SFHs) of galaxies at redshifts from the Carnegie-Spitzer-IMACS Survey includes confidence intervals that robustly distinguish late bloomers from "old" galaxies.

- 17 Dec 2018
TL;DR: In this article, the star formation histories (SFHs) of 24 massive galaxies at 1.6 50% of their extant masses by ~1.5 Gyr before the time of observed redshifts were studied.
