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: In this article, a self-organizing map is proposed to map the distribution of data in a high-dimensional space and projecting it onto a lower-dimensional representation, which can be used to estimate the additional spectroscopy needed to map out the color-redshift relation.

The relationship between infrared, optical, and ultraviolet extinction
TL;DR: In this article, the average extinction law over the 3.5 micron to 0.125 wavelength range was derived for both diffuse and dense regions of the interstellar medium. And the validity of the law over a large wavelength interval suggests that the processes which modify the sizes and compositions of grains are stochastic in nature.
