TL;DR: In this paper, a copula approximation to the low-l joint likelihood of the angular spectrum C l of masked cosmic microwave background temperature maps is proposed, which is both very accurate and very fast to evaluate.

TL;DR: In this article, a pair of related techniques were proposed to measure the two-point correlation function and the power spectrum with edge correction in any number of spatial dimensions, achieving unprecedented speed by using fast Fourier transforms for calculating a heuristically weighted, edge-corrected estimator for the twopoint function.

TL;DR: In this article, the authors report the most complete analysis of observations of the Cosmic Microwave Background (CMB) obtained during the 1998 flight of Boomerang and use two quite different methods to determine the angular power spectrum of the CMB in 20 bands centered at l = 50 to 1000, applying them to ∼ 50% more data than has previously been analyzed.

TL;DR: In this paper, the authors examined the morphology of long-wavelength dust emission as seen by Planck, including a study of its outermost spiral arms, and investigated the dust heating mechanism across M 31.

TL;DR: SITELLE as discussed by the authors is a Michelson-type interferometer able to reconstruct the spectrum of every light source within its 11' field of view in filter-selected bands of the visible (350 to 900 nm).
