The Grism Lens-Amplified Survey from Space (GLASS). XII. Spatially Resolved Galaxy Star Formation Histories and True Evolutionary Paths at z > 1
L. E. Abramson, A. B. Newman, T. Treu +12
Modern data empower observers to describe galaxies as the spatially and biographically complex objects they are. We illustrate this through case studies of four, systems…
Discovery of three strongly lensed quasars in the Sloan Digital Sky Survey
Peter R. Williams, Adriano Agnello, Tommaso Treu +12
We present the discovery of 3 quasar lenses in the Sloan Digital Sky Survey (SDSS), selected using two novel photometry-based selection techniques. The J0941+0518 system, with two…
Extreme magnification of a star at redshift 1.5 by a galaxy-cluster lens
Patrick L. Kelly, Jose M. Diego, Steven Rodney +42
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z=1.49 (dubbed "MACS J…
The Grism Lens-Amplified Survey from Space (GLASS). XI. Detection of CIV in Multiple Images of Ly Emitter Behind RXCJ2248.7-4431
Kasper B. Schmidt, Kuang-Han Huang, Tommaso Treu +11
The CIII] and CIV rest-frame UV emission lines are powerful probes of the ionizations states of galaxies. They have furthermore been suggested as alternatives for spectroscopic red…
