TL;DR: In this paper, the authors describe the Hubble Space Telescope imaging data products and data reduction procedures for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS).

TL;DR: The Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) as mentioned in this paper was designed to document the evolution of galaxies and black holes at $z\sim 1.5-8$, and to study Type Ia SNe beyond $z>1.5.

TL;DR: In this paper, the authors used high-precision photometry of red-giant-branch (RGB) stars in 57 Galactic globular clusters (GCs), mostly from the 'Hubble Space Telescope (HST ) UV Legacy Survey of Galactic GCs', to identify and characterize their multiple stellar populations.

TL;DR: In this paper, the star formation histories of six ultra-faint dwarf galaxies, Bootes I, Canes Venatici II, Coma Berenices, Hercules, Leo IV, and Ursa Major I, were analyzed using a combination of high-precision photometry obtained with the Advanced Camera for Surveys on the Hubble Space Telescope, medium-resolution spectroscopy obtained with DEep Imaging Multi-Object Spectrograph on the W. M. Keck Observatory, and updated Victoria-Regina isochrones tailored to the abundance patterns appropriate for these

TL;DR: In this paper, the authors build on the evidence provided by their Legacy Survey of Galactic globular clusters (GC) to submit to a crucial test four scenarios currently entertained for the formation of multiple stellar generations in GCs.
