TL;DR: The Dark Energy Survey (DES) photometric data set Y3 GOLD as discussed by the authors contains nearly 5000 deg2 of grizY imaging in the south Galactic cap including nearly 390 million objects, with depth reaching a signal-to-noise ratio ∼10 for extended objects up to i AB ∼ 23.0, and top-of-the-atmosphere photometric uniformity 98% and purity >99% for galaxies with 19 < i AB < 22.5.

TL;DR: In this article, the authors used the Weiland Family Stanford Graduate Fellowship (WFG) and the Office of Science of the United States Department of Energy (OSDE) to conduct an experimental study on the HST-HF2-51358.001-A.
Journal ArticleDOI
The Connection between Galaxies and their Dark Matter Halos
TL;DR: In this paper, the authors define the galaxy-halo connection as the multi-variate distribution of galaxy and halo properties that can be derived from observations and simulations and highlight key open questions about how galaxies and halos are connected.
