Deep Learning for CMB Foreground Removal and Beam Deconvolution: A U-Net GAN Approach
This paper introduces a U-Net-based Generative Adversarial Network (GAN) trained on realistic Planck-like simulations that successfully reconstructs high-fidelity Cosmic Microwave Background maps by simultaneously removing foreground contamination, instrumental noise, and beam convolution effects, achieving reconstruction errors below 1% outside the Galactic region.
