TL;DR: In this article, the authors investigated the contribution of secondary anisotropies induced by the transverse motions of clusters of galaxies to the CMB and derived the average contributions for three cosmological models.

TL;DR: In this paper, the authors give an overview of complementarity and synergy in cosmology between the Square Kilometre Array and future survey projects in other wavelengths, which can be very powerful to probe major cosmological problems such as dark energy, modified gravity and primordial nonGaussianity.

TL;DR: In this paper, the authors used the Hot Big Bang theory with the inflation hypothesis to detect very low contrast sub-horizon scale structures in the Cosmic Microwave Background (CMB).

Abstract: In the 1998-99 flight, BOOMERanG has produced maps of ˜ 4 % of the sky at high Galactic latitudes, at frequencies of 90, 150, 240 and 410 GHz, with resolution ≳ 10'. The faint structure of the Cosmic Microwave Background at horizon and sub-horizon scales is evident in these maps. These maps compare well to the maps recently obtained at lower frequencies by the WMAP experiment. Here we compare the amplitude and morphology of the structures observed in the two sets of maps. We also outline the polarization sensitive version of BOOMERanG, which was flown early this year to measure the linear polarization of the microwave sky at 150, 240 and 350 GHz.

TL;DR: In this article, an iterative multi-grid Jacobi algorithm is proposed to solve the optimal map making problem for next generation CMB experiments like ARCHEOPS and TopHat, and can probably be extended relatively easily to the full PLANCK case.
