We use the constraints set by the solar dipole seen with high signal to noise by all bolometers (100 to 353 GHz) to set with high accuracy the zero level of the HFI dust maps. This improves significantly the dust removal residuals.
The Planck satellite has measured CMB anisotropies on the full sky with unprecedented accuracy allowing pour cent precision on the measurement of cosmological parameters. This accuracy required
important mitigation of systematic effects which for some of the dominant effects were not anticipated before launch. In this presentation I will focus on Planck High Frequency Instrument (HFI)...
In this presentation I review the lessons learned from measuring and analyzing the microwave polarized sky with Planck, to extract the information encoded in the cosmic microwave background (CMB). I focus, in particular, on the challenge to control instrumental effects and calibration at the sensitivity level. This is crucial especially on large angular scales, where the noise is smaIl and the...
I will summarize some of the main lessons learned from Planck regarding efficient identification and mitigation of systematic effects, which will be essential for future CMB B-mode experiments. I will in particular highlight the tight relationship between instrumental systematics and astrophysical modelling, and the importance of addressing both of these aspects jointly. The presentation will...
