Planck intermediate results. LII. Planet flux densities
Planck Collaboration, Y. Akrami, M. Ashdown +147
Measurements of flux density are described for five planets, Mars, Jupiter, Saturn, Uranus, and Neptune, across the six Planck High Frequency Instrument frequency bands (100-857 GH…
Design of 280 GHz feedhorn-coupled TES arrays for the balloon-borne polarimeter SPIDER
Johannes Hubmayr, Jason E. Austermann, James A. Beall +40
We describe 280 GHz bolometric detector arrays that instrument the balloon-borne polarimeter SPIDER. A primary science goal of SPIDER is to measure the large-scale B-mode polarizat…
Planck intermediate results. XLVI. Reduction of large-scale systematic effects in HFI polarization maps and estimation of the reionization optical depth
Planck Collaboration, N. Aghanim, M. Ashdown +170
This paper describes the identification, modelling, and removal of previously unexplained systematic effects in the polarization data of the Planck High Frequency Instrument (HFI)…
Planck intermediate results. XLIX. Parity-violation constraints from polarization data
Planck Collaboration, N. Aghanim, M. Ashdown +148
Parity violating extensions of the standard electromagnetic theory cause in vacuo rotation of the plane of polarization of propagating photons. This effect, also known as cosmic bi…
