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…
Constraints on the spectral index of polarized synchrotron emission from WMAP and Faraday-corrected S-PASS data
U. Fuskeland, K. J. Andersen, R. Aurlien +8
We constrain the spectral index of polarized synchrotron emission, , by correlating the recently released 2.3 GHz S-Band Polarization All Sky Survey (S-PASS) data with the 23…
