BeyondPlanck II. CMB map-making through Gibbs sampling
E. Keihänen, A. -S. Suur-Uski, K. J. Andersen +37
We present a Gibbs sampling solution to the map-making problem for CMB measurements, building on existing destriping methodology. Gibbs sampling breaks the computationally heavy de…
BeyondPlanck XV. Polarized foreground emission between 30 and 70 GHz
T. L. Svalheim, K. J. Andersen, R. Aurlien +35
We constrain polarized foreground emission between 30 and 70 GHz with the Planck Low Frequency Instrument (LFI) and WMAP data within the global Bayesian BeyondPlanck framework. We…
BeyondPlanck VII. Bayesian estimation of gain and absolute calibration for CMB experiments
E. Gjerløw, H. T. Ihle, S. Galeotta +35
We present a Bayesian calibration algorithm for CMB observations as implemented within the global end-to-end BeyondPlanck (BP) framework, and apply this to the Planck Low Frequency…
BeyondPlanck VI. Noise characterization and modelling
H. T. Ihle, M. Bersanelli, C. Franceschet +38
We present a Bayesian method for estimating instrumental noise parameters and propagating noise uncertainties within the global BeyondPlanck Gibbs sampling framework, and apply thi…
Planck constraints on the tensor-to-scalar ratio
M. Tristram, A. J. Banday, K. M. Górski +14
We present constraints on the tensor-to-scalar ratio r using Planck data. We use the latest release of Planck maps (PR4), processed with the NPIPE code, which produces calibrated f…
A Monte Carlo comparison between template-based and Wiener-filter CMB dipole estimators
H. Thommesen, K. J. Andersen, R. Aurlien +8
We review and compare two different CMB dipole estimators discussed in the literature, and assess their performances through Monte Carlo simulations. The first method amounts to si…
Planck intermediate results. LVII. Joint Planck LFI and HFI data processing
Planck Collaboration, Y. Akrami, K. J. Andersen +136
We present the NPIPE processing pipeline, which produces calibrated frequency maps in temperature and polarization from data from the Planck Low Frequency Instrument (LFI) and High…
