TL;DR: The Hierarchical Equal Area iso-Latitude Pixelization (HEALPix) as discussed by the authors is a data structure with an associated library of computational algorithms and visualization software that supports fast scientific applications executable directly on very large volumes of astronomical data and large area surveys in the form of discretized spherical maps.

TL;DR: In this paper, the power spectrum and N-point correlation functions of the Wilkinson Microwave Anisotropy Probe (WMAP) first-year data were used to measure the amplitudes of the large-scale fluctuations on opposing hemispheres and study the ratio of the two amplitudes.

TL;DR: In this paper, two independent but complementary statistical analyses of the WMAP first-year data, based on the power spectrum and N-point correlation functions, are presented. But the results are stable with respect to the choice of Galactic cut and also with respect with the frequency band.

TL;DR: In this paper, the authors describe the all-sky Planck catalogue of clusters and cluster candidates derived from Sunyaev-Zeldovich (SZ) effect detections using the first 15.5 months of Planck satellite observations.

TL;DR: The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009 as discussed by the authors, and it will continue to gather scientific data until the end of its cryogenic lifetime.
