TL;DR: In this paper, the authors proposed a method to constrain the probability distribution function of the effective line-of-sight convergence (kappa) by matching the observed overdensity in the weighted number of galaxies to that found in mock catalogs with {kappa}{sub ext} obtained by ray-tracing through structure formation simulations.
Flux-averaging Analysis of Type Ia Supernova Data
TL;DR: In this paper, the authors combined the SN Ia data from the High-z SN Search and the Supernova Cosmology Project and binned the combined data by flux-averaging in redshift intervals of Δz = 0.05 and Δz= 0.1.

Dark energy constraints from the thermal Sunyaev–Zeldovich power spectrum
TL;DR: In this paper, the authors constrain the dark energy equation of state parameter, $${w}$$, using the power spectrum of the thermal Sunyaev-Zeldovich (tSZ) effect, and they find that the amplitude of the tSZ power spectrum at l ≲ 10^3 depends primarily on F ≡ σ_8(Ω_m/B)^0.06 (68 per

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.
