B-mode constraints from Planck low multipole polarisation data
Roger de Belsunce, Steven Gratton, George Efstathiou
We present constraints on primordial B modes from large angular scale cosmic microwave background polarisation anisotropies measured with the Planck satellite. To remove Galactic p…

Testing for spectral index variations in polarised CMB foregrounds
Roger de Belsunce, Steven Gratton, George Efstathiou
We present a Bayesian parametric component separation method for polarised microwave sky maps. We solve jointly for the primary cosmic microwave background (CMB) signal and the mai…
