TL;DR: In this paper, the authors present constraints on extensions of the minimal cosmological models dominated by dark matter and dark energy, ΛCDM and wCDM, by using a combined analysis of galaxy clustering and weak gravitational lensing from the first-year data of the Dark Energy Survey (DES Y1) in combination with external data.

TL;DR: Amon et al. as mentioned in this paper present cosmic shear measurements and cosmological constraints from over 100 million source galaxies in the DES Year 3 data, and compare their measurement with constraints from two other contemporary weak-lensing experiments: the Kilo-Degree Survey (KiDS) and Hyper-Suprime Camera Subaru Strategic Program (HSC).

TL;DR: In this article, the authors present the Dark Energy Survey Year 3 cosmic shear measurements and cosmological constraints based on an analysis of over 100 million source galaxies, with the data spanning 4143 deg$^2$ on the sky, divided into four redshift bins, with a signal-to-noise of 40.4 dB.

TL;DR: Combined results from these probes derive constraints on the equation of state, w, of dark energy and its energy density in the Universe, demonstrating the potential power of large multiprobe photometric surveys and paving the way for order of magnitude advances in constraints on properties ofdark energy and cosmology over the next decade.

TL;DR: In this article, a fiducial covariance matrix model for the combined 2-point function analysis of the Dark Energy Survey Year 3 (DES-Y3) dataset is presented.
