Description
I will present recent results of field level inference applied to three different cosmological probes. In the case of gravitational lensing of cosmic microwave background, explicit field level inference can extract both the lensing potential and delensed CMB. Recent developments in MCMC sampling have enabled full hierarchical Bayesian analysis. For galaxy clustering and Baryonic Acoustic Oscillations, both explicit and implicit field level inference are being developed, and I will present recent results and future prospects. Finally, I will present results from implicit field level inference applied to galaxy shear data. In all cases, field level inference leads to significant improvements over the current state of the art analyses.
