TL;DR: Cosmological constraints from the analysis of two-point correlation functions between galaxy positions and galaxy lensing measured in Dark Energy Survey (DES) Year 3 data and measurements of cosmic microwave background (CMB) lensing from the South Pole Telescope (SPT) and Planck suggest possible problems with the correlation function measurements using alternative lens galaxy samples.

TL;DR: PolyChord is investigated to motivate and validate the algorithm and settings used for the Dark Energy Survey analyses of the first 3 years of data from combined measurements of weak lensing and galaxy clustering, and is determined to provide a good balance of speed and robustness for posterior and evidence estimation.

TL;DR: In this paper, the authors present an approach for creating science-ready catalogs through a software infrastructure developed for the Dark Energy Survey (DES), which integrates the data products released by DES Data Management and additional products created by the DES collaboration in an environment known as DES Science Portal.

TL;DR: In this paper, the authors report on small-amplitude optical variability and recent dissipation of the unusually persistent broad emission lines in the blue compact dwarf galaxy PHL 293B.

TL;DR: High signal-to-noise measurements of three-point shear correlations and the third moment of the mass aperture statistic using the first 3 years of data from the Dark Energy Survey are presented and it is determined that the measured signals are likely to be of astrophysical and gravitational origin.
