Planck 2018 results. IV. Diffuse component separation

Planck Collaboration, Y. Akrami, M. Ashdown +150

We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps. These pr…

Physics-Informed Graph-Neural Decoding of the Surface Code: the Logical Signal as an Exact Topological Pairing

P. E. Trevisanutto, S. Dhanpal, S. Basak +2

We develop a physics-informed graph neural network (GNN) decoder for the surface code that solves a discrete Poisson equation on the syndrome graph, with the syndrome as the charge…

The pre-launch Planck Sky Model: a model of sky emission at submillimetre to centimetre wavelengths

J. Delabrouille, M. Betoule, J. -B. Melin +39

We present the Planck Sky Model (PSM), a parametric model for the generation of all-sky, few arcminute resolution maps of sky emission at submillimetre to centimetre wavelengths, i…
