HIGHLIGHTS
- who: Planck Collaboration and colleagues from the (UNIVERSITY) have published the Article: Planck 2018 results - XI. Polarized dust foregrounds, in the Journal: (JOURNAL)
- what: By fitting multi-frequency cross-spectra between data at 100 143 217 and 353 GHz the authors examine the correlation of the dust polarization maps across frequency. If the limit on decorrelation for the largest sky region applies to the smaller sky regions observed by sub-orbital experiments then frequency decorrelation of dust polarization might not be problem for CMB experiments aiming at primordial B-mode detection limit on the tensor . . .
