Using Cross-Correlations to Calibrate Lensing Source Redshift Distributions: Improving Cosmological Constraints from Upcoming Weak Lensing Surveys
TL;DR: In this article, the authors consider a scenario where photometric redshifts are available, and find that, unless the redshift distribution p(z_{ph}|z) is calibrated very accurately a priori (bias and scatter known to ~0.002 for, e.g., EUCLID), the additional constraint from the cross correlation technique to a large extent restores the cosmological information originally lost due to the uncertainty in dn/dz(z).
Journal ArticleDOI
No need for dark matter in galaxy clusters within Galileon theory
TL;DR: In this article, an extension of covariant Galileon models in the so-called ''beyond Horndeski'' scenario is considered, where a breaking of the Vainshtein mechanism is possible and, thus, some peculiar observational signatures should be detectable and make it distinguishable from general relativity.

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.
