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…
Cosmology with the CMB temperature-polarization correlation
F. Couchot, S. Henrot-Versillé, O. Perdereau +4
We demonstrate that the cosmic microwave background (CMB) temperature-polarization cross-correlation provides accurate and robust constraints on cosmological parameters. We compare…
Agnostic cosmology in the CAMEL framework
S. Henrot-Versillé, O. Perdereau, S. Plaszczynski +3
Cosmological parameter estimation is traditionally performed in the Bayesian context. By adopting an "agnostic" statistical point of view, we show the interest of confronting the B…
Planck intermediate results. XLV. Radio spectra of northern extragalactic radio sources
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active galactic nuclei, based on f…
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…
