TL;DR: Archeops as discussed by the authors is a balloon-borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (8 arcminutes) over a large fraction (25%) of the sky in the millimetre domain.

TL;DR: In this paper, a broadband log-periodic antenna coupled with multiple cryogenic bolometers is proposed to simultaneously receive two linear polarizations with two octaves of bandwidth at millimeter wavelengths, where the broad bandwidth signal is divided into sub-bands with integrated in-line frequency-selective filters.

TL;DR: In this paper, the authors investigate the science goals achievable with the upcoming generation of ground-based cosmic microwave background polarization experiments, focusing on one particular experiment, QUaD [QUEST (Q and U Extragalactic Submillimetre Telescope) and DASI (Degree Angular Scale Interferometer)], a proposed bolometric polarimeter operating from the South Pole.

TL;DR: In this article, the authors presented a new upper limit on cosmic microwave background (CMB) circular polarization from the 2015 flight of SPIDER, a balloon-borne telescope designed to search for B-mode linear polarization from cosmic inflation.
