Journal ArticleDOI
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.
Journal ArticleDOI
Detection of a Dark Substructure through Gravitational Imaging
TL;DR: The detection of a dark substructure through direct gravitational imaging is reported in this article, which is based on a Bayesian grid reconstruction of the two-dimensional surface density of the galaxy inside an annulus around its Einstein radius.
Journal ArticleDOI
The Sloan Lens ACS Survey. XI. Beyond Hubble resolution: size, luminosity and stellar mass of compact lensed galaxies at intermediate redshift
Elisabeth R. Newton,Philip J. Marshall,Philip J. Marshall,Tommaso Treu,Matthew W. Auger,Raphael Gavazzi,Adam S. Bolton,Léon V. E. Koopmans,Leonidas A. Moustakas +8 more
TL;DR: In this paper, the authors exploit the strong lensing effect to explore the properties of intrinsically faint and compact galaxies at intermediate redshift, at the highest possible resolution at optical wavelengths.
Journal ArticleDOI
Robotic reverberation mapping of the broad-line radio galaxy 3C 120
Michael S Hlabathe,D. A. Starkey,Keith Horne,Encarni Romero-Colmenero,Steven M. Crawford,Stefano Valenti,Stefano Valenti,Hartmut Winkler,Aaron J. Barth,Christopher A. Onken,David J. Sand,Tommaso Treu,Aleksandar M. Diamond-Stanic,Carolin Villforth +13 more
TL;DR: In this article, the authors acknowledge support from the South African National Research Foundation (SARF) and the Space Telescope Science Institute (STScI) Director's Discretionary Research Fund (DDRF).
Journal ArticleDOI
Overdensities of Y-dropout Galaxies from the Brightest-of-Reionizing Galaxies Survey: A Candidate Protocluster at Redshift z~8
Michele Trenti,Larry Bradley,Massimo Stiavelli,J. M. Shull,Pascal Oesch,Rychard Bouwens,Rychard Bouwens,Joseph A. Muñoz,Emilio Romano-Diaz,Tommaso Treu,Isaac Shlosman,C. M. Carollo +11 more
TL;DR: In this article, the authors extend the search for Y-dropouts to fainter luminosities (M_* galaxies with M_AB\sim-20), with detections at >5σigma confidence (compared to >8sigma confidence adopted earlier) identifying 17 new candidates.
