Final BeyondPlanck data release coming soon!

New constraints on the polarized microwave sky

First combined constraints on polarized synchrotron emission from Planck and WMAP

Global Bayesian Cosmological Parameter estimation

End-to-end propagation of instrumental and astrophysical uncertainties from raw time-ordered data to final cosmological parameters

Joint calibration and foreground estimation

Breaking degeneracies through multi-experiment analysis and global modelling

Realistic low-level instrument modelling

BeyondPlanck supports both realistic and flexible data models, including 4pi sidelobe beam convolution, time-dependent noise characterization, and tunable bandpass profiles

Frequency maps with sample-based noise propagation

• Full sky signal at 30, 44 and 70 GHz including CMB dipole
• Correlated noise propagation at full angular resolution with Monte Carlo sampling

CMB constraints with novel sample-based likelihood

• End-to-end error propagation
• Computationally efficient CMB likelihoods
