TL;DR: In this article, the authors present a new measurement of EG, which combines measurements of weak gravitational lensing, galaxy clustering, and redshift-space distortions, and find that their measurements, as well as existing ones in the literature, favor a lower matter density cosmology than the cosmic microwave background.

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.
